Came across this picture on here (of different dash switches, the corner sensor and half mast are weird!, the heated mirror switch is 2nd from the end) from a while back and was wondering where you would find info on original factory options for a 2 door 2004/05 Civic EX coupe? I've looked high and low on the net to no avail. So I figured you guys on here would have some of these and know about them. I know of course there were paint color options and trim (HX,EX, Lx,etc.) What I'm namely talking about is what did the dealer offer in the name of interior/exterior options(in the USA) to upgrade your car? I know the OEM foglights were def. an option, as were the moonroof w/switch, cruise I'm assuming, power mirrors, leather seats? What about rims/alternatives for the 2001-05 years? I'm thinking about adding heated seats and/or heated mirrors with OEM switches because of where I live. I have one port left in my center console as you can see below. Does anyone on here have heated seats or heated mirrors on their EM2 or installed them later on? Let me know of any factory options that you know about and where you can find a list of original dealer options for 04/05 civic coupes or even the 2001-03 EM2s. Also part#'s would be nice for heated seat and heated mirror wiring kits w/OEM switch part #'s. Thanks!

 

Nobody on here (besides CA residents who don't need them, haha) has heated seats for an EM2 or knows how to wire them underneath the seats? I found the part # on here (someone used for a 1994 Civic, I believe) for a 2/1 Acura OEM heated seat switch which is P/N 38535-SS8-A01. Heard Honda's have each OEM switch separate for each seat which means using 2 ports which I don't want to do. Please let me know if you have this option on your car or have installed it yourself. Any help is appreciated.

 

interesting...

anyways..i have factory heated mirrors. the switch is a little thing located on the power mirror adjustment stuff. i rarely use my heated mirrors though. you can get factory heated mirrors from a canadian car. i believe they were available on the civic si-g (si coupe might have them too) coupes or lx sedans.

 

Acura EL prts numbers:
Heated Seat Switch(similar to one previously shown above, except horizontial instead of vertical) 38535-S5N-C01ZA
Heated seat elements 81134-S5A-E11, same left and right
Harness to run this is complete floor harness, parts numbers 32107-S5N-C10 (2001), AND 32107-S5N-C32 (2002). Have not got to see one of these yet in a yard to see how much work in would be to make fit in a Civic.

 

Thanks for those part #'s. I talked to an Acura dealer and they said those parts may or may not be compatible with a honda even though they do share some of the same stuff. They weren't much help, only told me that the new 2010 Civic EX's were going to offer heated seats. Do you know if those part #'s are for comparable years of Acura's/Honda's like 2001-2005 or newer/older models? Do those seat heating elements come with harness wiring diagrams, instructions, like the OEM foglights do?I would assume that they do. That vertical 2/1 switch (that I have a picture of above) I guess could go to a 1997 Acura or be installed by the emergency brake for a 1994 honda civic from my research. Also the dealer said the car would have to be "pre-wired" from the factory to be able to install heated seats on a civic. He said they were "pre-wired" for optional foglights to begin with but wasn't sure about the seats. There are 2 plug in connectors under my seats (one for yellow airbag plug I think), and another for God knows what, I'm thinking that the heat element would have to be hooked up to one of those, could be wrong I guess. An other problem I was having was whether I can install the heating elements inside leather seats or not. Found a different switch (for dash) on heatedseatkits.com (picture below). I might try that route and take out my air conditioning circulator? button (next to A/C and rear defog) or drill a new 20mm hole in the dash. Again, wondering about the wiring. If I do figure this out, will provide a DIY on here! Sorry to ramble....

 

Well, here are your Honda USA Dealer Accessories. You can still purchase these at the dealer for a 2005 model year car. But, I think you already knew this?

Your heated seats and heated mirrors options were not available in the US, I don't think. These would have to be DIY upgrades based on parts from other vehicles. Your best bet would be from a Canadian Acura EL - this is the exact same platform as the Civic - which came with more premium and/or Canadian-specific options. EDIT TO CLARIFY: I don't believe (but don't quote me on this) that heated seats/mirrors were a dealer upgrade or accessory. These were most likely factory standard features for some trim levels.

Both of these upgrades will transfer over cleanly and perfectly, provided you do your research on what parts you need and go out and get them yourself. Don't listen to the guy at the dealership, he's only interested in plug-n-play options, and will tell you it can't be done because he doesn't know any better. Take it from me, as a guy who added OEM Civic headlight washers to my 5th Gen, if I went to the dealer and asked "can I add headlight washers to my Civic?", I would have been told to get lost, in no uncertain terms.

The 05 Civic Coupe in Germany came with the 38535-S5N-C01ZA switch installed, so I know it can be done. Although, on the European parts diagrams, it still looks like a vertical switch (not horizontal), but that might be incorrect (it really wouldn't look right.)

Speaking of not looking right, the fog light switch in the first post is installed upside down.

 

The fitment of the aftermarket seat heaters doesn't depend so much on the material of your seat covers (leather/cloth, etc.) but of how the seat covers are attached to the foam. The elements are not really compatible with seats that have vertical (front to back) stitching.

 

Thanks for all the great info guys! I'm determined to get the heated seats installed, but I do need the horizontal switch for my center console. I will post back with any progress.

 

After much research...some progress! I found the OEM honda switch that will fit the 05 Civic EX console (which was my main priority since you don't see the wiring harness or seat heating elements anyhow) but I'll need it to get it from a different vehicle. It amazes me how the Odysseys, Accords, etc. came with heated seats around the 2001-2005 time frame, but not the Civics? Unreal. The stumbling block I'm having right now is the wiring harness that runs from the seats to the under dash fuse box. Factory one is 778.34 that I'll probably need, cheapest price I found was $493.07! Looks like the boneyard is in my future!! Oh yeah BTW, the cheapest heat elements for EACH seat from the dealer I found were $252! Outrageous, looks like aftermarket heating elements will have to do. More later on.....

 

it is supposed to be a vertical switch and there is supposed to two (one for each seat) behind the shifter and before the handbrake they have them in the UK version of the car along with the heated power mirrors. and the heated power mirrors switch is on the electronic adjustable mirror switch

 

All right, here's the possible solution that I've found if anyone wants to attempt a DIY on this. Guys good with wiring, Cardenas?, anyone else? The 04/05 civics (not sure about 01-03's) parts are very similar to what was used in the 05/06 CR-V's. I've compared the two consoles and under dash fuse boxes, they look pretty much identical. Part # 38535-s9a-s01z (vertical heated seat switch for the CR-V) will def. fit the center and left of steering wheel consoles on the 04/05 Civics. I need a HORIZONTAL heated seat switch personally(like my OEM center console foglight one) because of only having 1 available slot left in my center console, but these weren't offered horizontally set up. Each individual heat seat element from CR-V, Parts # 81134-s9a-a71 looks like a go to install or you can purchase some aftermarket ones from heatedseatkits.com. Here's the problem: the wire harness from the CR-v that hooks to the underdash fuse box, part # 32107-s9a-a23 is probably what you need to have a clean OEM look and have it done right. Lowest cost online I could find was $500 for this one part! This wire harness was ONLY available on the 2006 CR-v 5 door SPECIAL EDITION (very tough to find in a boneyard!, I would rip it out myself at the junkyard if I could) and all other wire harnesses for 05/06 CR-v are different part #'s and set up different because of not having the heated seat option. So there you go, I know it can be done but you have to have those parts to use an OEM switch in a Civic, possibly. I'm sure someone can figure out a way to use the heatedseatkits.com elements and harness (alot cheaper $$ option) with the OEM switch part I just told you about. I've seen it done with the Ebay foglights and using an OEM Honda fog switch. Again, someone good with wiring (not me). Let me know if someone figures this out, just give me some credit on your DIY (haha). Good luck!!!

 

You could source Canada as a place for your switches. Here's a place with three 2001 Acura ELs. http://www.davesautoparts.on.ca/asp/parts/ At least one vehicle should have your horizontal switch.

Nevermind about the correct wiring harness, just use aftermarket wiring (or do what I do, and pluck the correct colour wires from salvage yard wrecks). Aftermarket heater pads will work just fine (trust me, as someone who's already installed them in my Civic) and are very affordable. The relay for the switch (not the one for the seat elements) is most likely a Mitsuba RC-2201. These are used on many, many Honda vehicles.

The wiring will be similar, if not identical to the CR-V Heated Seats diagram I have attached. Pin-out from the under-dash fuse box will be different, though. EDIT: A check of the 03 Civic vs 06 CR-V fuse boxes in the parts diagrams shows that they are pretty similar. Might be the same pin-outs.

 

^ How did you get those diagrams? Nice! Come do my seats ,you're a genius with wiring! Haha. I just saw you used the dual vertical switch by the shifter/ emergency brake, correct?; and those hog rings for the upholstery (which I'm not looking forward to messing with btw! I physically went on the dealer's lot recently and just sat in the 2006 CR-v Special Edition (with the heated seats) and had my car (2005 Civic EX coupe) pulled up next to it. (Got the idea to do this from my Hayne's repair manual,look at cover if you have one). The guy thought I was nuts when he asked me if I wanted to go for a test drive and I said "no, I'm just going to pull off your CR-v's under dash cover and compare the console switches and under dash fuse boxes." I starting tearing apart the CR-V, he was mortified, I'd pay for the look on his face! Then he realized that he was the one that originally sold my car to me and asked me what in the hell happened to it (meaning all the changes I did to it, said it didn't even look like the same car, Lmfao).
Anyhow..., I don't like the round dash switch that comes with the heatedseatkits. com kit and having to drill out a 20mm hole, thus my wanting to use the Honda OEM horizontal switch (still haven't found one for heated seats, but will check your info) but not good with crazy custom wiring. Did you use the harness with that kit and have to alter the wiring to fit your OEM switch, did it come with the relay? Just curious! thanks!

 

To clarify:

I spotted a 01-05 Acura EL last weekend and peeked inside to confirm if it had those horizontal OEM heated seat switches, and it did. So, contact the wreckers above that I linked to and get the switch from one of their EL wrecks.

For my project, I mated the OEM EDM wire colour for "power" (WHT/BLK on my 5th Gen Civic) that emerges from the OEM switch to the "power" wire on the aftermarket heated seat kit. You can just barely see the connection at the top of the following photo, labelled as #3 (photo is from my DIY).



As you see from the wiring, the WHT/BLK (actually, I just Sharpie'd over a WHT/RED wire) emerges from the green connector at #2.

The wiring from this point goes to the seat heater element, and all the extra wiring from the kit, including that round switch, is coiled under my seat and out of the way:


The round switch is just permanently set to "ON" (Low), except in the summer when I turn it to "OFF" so I don't boil if I accidentally turn the OEM switch on.

Also, and importantly, there is NO RELAY for the seat heater elements that comes with the kit. It is not needed, so it is one less thing to worry about.

Don't be scared about the wiring, you'll see it's not that tricky once you get the hang of it. Follow the diagrams and think it through. I find it rewarding using the OEM wiring colours, but this is really not a necessity. You can purchase wiring at any respectable automotive parts store.

 

I completed this install last fall on a friend's 2004 Civic: Seat heaters were pulled from a CDM Acura 1.7EL, along with OEM wiring (pulled and cut, then spliced back together - pulling entire harnesses is a major pain). I managed to find the correct horizontal switch, too, which is possibly the trickiest part to happen across (I got lucky). Install followed OEM wiring diagrams, and run alongside existing harnesses. Looks and works great!
