Ok finally after a while I got tired of reading "how do i wire up a S2K start engine button" no one really had any good writeups or explanations. Even on HT all I see is "Im gonna do it and write up DIY" but they never do.

Ok first of all for all you blingy people who want a fancy button you can get the S2K push start button for 30 somethign at honda. or if you want to be sleeper and you dont care about Cruise control, you CAN use your cruise control button as a push start button too. The S2K button I got "used" seems to be faulty so i tried out the cruise control button and I lucked out it too also works.

BUT a warning due to teh design of the switch inside of the cruise control, the switch is not momentary. meaning you push it in and it stays pushed in. So imagin that it is liek turning the key, after you start the car think of what happens if you leave the key still turned forward? you hear this screeching sound of the starter motor trying to start a running engine. well same thing. as soon as the engine craks over push the cruise control again to release it. if you use the S2K button you jsut hold it down then let go.

Here is what you need

S2K button (or use your cruise control button)
if you use the S2k button you need 77266-ST7-003ZA LID ASSY., VISOR SWITCH to make a collar for the button
relay 30A BOSCH SR-2 Relay
female connectors
inlne connectors.
wire cutter/stripper/crimp
flat screwdriver
phillips screwdriver
10mm socket wrench

Ok one of the biggest confusion for the S2K button is where to find a suitable harness for the 5 pins?

You only need three pins, two of them dont do anything. but I found the perfect harness . . .

CRUISE CONTROL!!!!


I pulled out the cruise control button and noticed that it too has 5 pins. the harness plug needed a minor modification to make it fit in the S2K button.

So here we go.

pull out the cruise control button. it helps to use a flat screwdriver. Unplug the baby blue harness plug

If you look at the back of the S2K button and the Cruise control button you will see that the cruise contrl button has a vertical channel on the left side. that matches up with a small piece of plastic that sticks up from the harness plug. cut that little piece of plastic and try to fit the blue plug into the S2K button. keep trimming that piece down to make the plug fit in the s2k button.
Look at the right hand side of the plug in the pic below



Remove the steering column cover and under dash cover

also the knee bolster metal thing remove that too.

Go back to the cruise control button hole and look for the baby blue harness plug. reach underneath the dash and pull it out. cut the harness off and give plenty of slack for wire tapping.

You will need to find the thick loom under the steering column. cut the loom open but be careful not to cut any wires.

There should be a few black tubes. im not sure which one it is but you need to keep opening each one to find the black with yellow stripe and black with white stripe.

Blk/wht is for the starter
blk/ylw is for the ignition.

cut these wires. there will be two ends. one that goes up to the key cylinder and the other side going down and that goes to the motor.

Ok so look at the diagram for the wiring. It looks retarded and complex but it is not




Here is a picture that shows the position of the relay points and their corresponding numbers


Now look at this picture.

See how the top two wires are not being used? and the bottom three are? (if you go back and look at my crappy diagram the picture of the button board is looking at it from the back side)
Well using the picture above as orientation. here is the wiring.
(reference my diagram for which is what wire)

Use the female adapters to plug into the spade connectors on the relay

A wire (bottom wire in pic)-> #86 on relay
B wire (middle wire in pic) -> motor side ylw/blk ignition wire
C wire (top wire in pic) -> #85 on relay (use another length of wire and tap into 85 and C-wire to ground it to any bolt under the dash.

#87 on Relay -> blk/wht motorside starter wire

#30 on relay goes to 12V power in fuse box. look at the picture it is the red female adapter circled in red there are other points that have 12v too I just used that one. If you have a test ligth you can check for 12v power when the key is turned to ON.


You are done. test it out by stepping on the clutch. put your key in the ignition and turn to ON (position right before cranking starter also the dash lights will all come on) Now push the button and car should start.

this configuration will disable the key from starting the car.

IF you want to KEEP the key starting feature then reconnect the ylw/blk wire ends. so you jsut tap the #87 from relay into the ylw/blk wire.


Also if you are using the S2K button then you need to take the 77266-ST7-003ZA LID ASSY., VISOR SWITCH cover and cut a hole in the center for the switch to fit in. there are some ridges on the button cylinder that you may need to shave off.


I do not take any responsibility for your car if you make a mistake. If you cut the ylw/blk wire and blk/wht wire that will void your warranty. If some how it doesnt work. then reconnect the blk/wht and blk/ylw wires.

Although i am totally confused this will be a good writeup once i figure it out

So let me get this straight, you cut off your CC harness and add those 3 wires which then directly hook up to the spade connectors on the relay? what happens after that and where does that green circuit bored come from... im confused.

Ok i think i figured it out,
1. A 12v from the fusebox goes to the relay
2. starter wire goes to relay
3. ground goes to relay and a bolt
4. ignition wire goes to button
5. and the button goes to 86 on the relay

yeah. you got it. the Green board is a picture of what the inside of the S2K button looks like.

alex_s817

hey Solscud007, i was just wondering if you know how to do this but also eliminate the key? like maybe wire a hidden switch so when you flick it, the ignition would turn on. just thinking but good write-up

Solscud007

if you re-read my DIY, i know its sort of confusing, it does eliminate the key

or do you mean eliminate the need for the key entirely? no I do not know how to do that but it sounds convienent but easier for your car to be stolen. the whole reason for the key is to try and prevent people fron jsut pushing a button and startign your car.

alex_s817

yea i meant completly eliminate the key altogether. i understand it would make it easier to steal the car, and the wheel wouldnt be able to lock. i think it would be pretty cool if you mounted the switch in a hidden spot that is easily accessible like under the cup holder or something, then all you do is reach under and flp the switch, push the button, and it starts right up

Solscud007

well it is possible because think of remote engine starters

They dont need the key either. figure it out and do a write up. But if you are gonna do thru all that trouble might as well do a remote engine starter.

update:

Here is a pic of the S2K button in place of the dimmer switch. I want to move the start engine button here as it is right next to the key. But what to do with dimmer ****? well the **** itself can come off. as i was tryign to pop out the entire switch the little flange collar broke and the whole switch fell back into the dash. oh ok oops. but actually that helps me cause i dont use the dimmer at all anyway (YOU MUST KEEP THE DIMMER PLUGGED IN other wise you will no longer have dash lights)




I also jsut picked up a jdm amber foglight switch from hmotorsonline for 20 bucks and it came with teh harness. the harness is exactly the same as the cruise control harness.


So right now im using this as my push start until i get a replacement S2K button

JDM itrs dont have dimmers or cruise control so i think this is the same cover plate i was talking about. I need to confirm if USDM ITRs are the same



you cut it like this


and then put the S2K button inside it l;ike in the pic above.

That's awesome! If I had the time or the skills i would do it myself.

it really isnt that hard. Its jsut connect one wire here and there and then splice into your starter and ignition wires.

im going to do this once my button from hondaautomotiveparts.com comes.. local deal wants like $65!

uh ok gl

tyco

bring this thread back to life, good write up!

mtgTINT.com

Great write up very complete. I literally just did it. I started at noon and just finished at 4 this afternoon. The wiring and everything didn't take long at all. I thought I had everything wired up right but it just wasn't working. I started connecting random wires and it started! The wire that wasn't connected right was the ignition wire (blk/ylw). It was wired to the button ok, but the write up failed to mention that the ignition wire shouldn't be cut, but rather tapped into. It now works perfectly...thanx for the info Solscud007.

boostin350z

so can you use your cruise control and have this starter button?

keepinitrehaal

bump!

webbs2jzgte

very good write up. quick question when you say eliminates the key do you mean the key will release and pull out of hte lock cylinder or will you just turn the key to on hit the push button and than just leave the key in their. also you said cut a whole int eh switch you meant eh cruise control right not the s2k button?

Awesome write up, i want to do this next summer when its warm

No, this thread explains how to use a DC integra cruise control harness with a s2k start button.

Using a Cruise Control button, you would have to press the button to start and press it again once the car is started so it wont continue to engage the starter while the engine is already started.

mtgTINT.com

I just used my cruise control button, not an s2k button. Now I don't have cruise control but I've never used that anyway. It's very stealthy, and I wired all the wires in a black loom, so to a thief, it would take them a while to figure out whats goin on down there. And remember when it says the switch or button has to be momentary..I thought so too, but I just press my cruise control button and it stays in and the starter doesn't grind at all. I found this out by accident because the first few times i tried it, I pressed the button, waited til it started, then pressed it again, but turns out you don't have to press it off.

mtgTINT.com

Like I said, I just did this in my car, and you had an interesting question, so I just tried it out...You have to leave the key in the on position and leave it there. The key still does everything it used to except crank the starter. The key still turns off the car. The reason I did it is because it's kind of a anti-theft thing. you need the key and you need to know that the CC button is actually the start button. So even though it might be cool to have a push start button, don't tell anyone cause word travels fast.

As an update to the wiring on this thread. I used the ign switched 12v from the fusebox like the OP used. However, this worked for maybe 2 weeks before I blew the Heater/AC 7.5A fuse. I replace the fuse and worked for two days before it popped again. Even though it is more convenient to connect the switched 12v wire to the fusebox because it requires no splicing, I highly suggest running the switched 12v wire to the fat black/yellow switched 12v wire running from the fusebox since you are already splicing into the fat black/white starter wire.
