Anyone ever manage to do this in a OEM manner on a 6th gen coupe?

I have a HX with a viper 4 button alarm system, and I really want to get this to work.

The 6th gen latch:
The factory civic trunk latch has the keyswitch in the trunk lid or the remote cable release.
The part number is:
74851-S01-A01 (#8 on the diagram)
Majestic Honda

I believe this latch is standard across all 6th gen civics. As you can see, the cable enters the latch from the left hand side of the vehicle.

Notice the mounting. 3 holes in a triangle pattern.

Next I did some googling, and found this: 7th gen install how-to
At first glance, this was exactly what I was looking for. Don' be fooled though.

The 7th gen latch:
2-door
The part number is:
74851-S5A-A02 (#11 on the diagram)
Majestic Honda
There are also 3 other latches on the diagram (12, 41, and 52) which are not listed. I am not sure what these do or if these are electric. Maybe a 7th gen owner can give input if 7th gens ever came with factory electric release.

4-door
Only 2 latches shown on this diagram (12 and 13). 12 is part number 74851-S5A-A02, the same as the 2-door part. 13 is not listed.
Majestic Honda

Notice that the mounting is different. There are 2 holes diagonally across from each other.

From this, I went to the 6th gen accord (98-01)
The 6th Gen Accord Latch
This latch mounts the same way as the 7th gen civic (as shown by the write up). There are 2 holes that are diagonally opposite each other. I went and bought a used latch from a junk yard, to see if it would work in the civic. Notice the cable enters from the top on the left hand side, not the left. This was ok in the write up, as the cable had extra slack to account for this. The same would be true in a 6th gen, but the latch will not mount up. The lockrod attachment will not fit through the hole into the trunk (it is .5 inches too low), the bolt holes do not line up, and the larger mounting bracket (especially the 2001 model with the trunk release lever) will not fit within the sheet metal of the civics trunklid.

The Part Number is:
74851-S84-A41 (#12 on the diagram)
Majestic Honda

#49 on the diagram (74851-S84-A11) fits the 2001 VP model, which apparently did not get the automatic release.


The 5th Gen Accord Latch
I looked at the 96 accord (94-97) to see if it came with the optional electric trunk release. From what I can see, It was not optional.
The Part Number is:
74851-SV1-003 (#14 on the diagram)
Majestic Honda

This latch looks like it mounts in a completely different way than the 6th gen civic latch. It seems to mount through a hole in the trunk lid, and not from behind. There isn't a rubbery sleeve to protect the latch as shown in the other diagrams.


Other Cars?
S2000
My buddy has a s2000, but I havent had a chance to look at that one yet. It seems from Majestic's diagrams that it is completely straight and not bent at all (so will not even come close to fitting).

The Part Number is:
74851-S2A-003 (#11 on the diagram)
Majestic Honda


4th gen Prelude
The Part Number is:
74851-SM4-003 (#18 on the diagram)
Majestic Honda
This looks alot like the 5th gen accord's latch.


5th gen Prelude
The Part Number is:
74851-S30-003 (#16 on the diagram)
Majestic Honda
Looks like the 5th gen was not offered with a electric trunk release? I cannot tell from the picture. There is a second latch that is shown (44) but not listed below. Can anyone confirm if the prelude was offered with this feature?


Integra
Would think this would be the best shot, since alot of parts are shared between the 6th gen civic and the 3rd gen integras. Would have to be a 4 door though to have a trunk I would think.
The part number is:
74851-SK8-023 (#9 on the diagram)
AcuraPartsOnline

This latch looks like the civic latch from what I can see, with 3 mounting holes in a triangle. I am unsure what is different in order to account for the new part number

There is also another latch shown but not listed, (#40), which might be the updated part for the 01 cars. In 01, the government mandated the glow in the dark trunk release buttons.

yep, looking up for the 2001 car you get no #9 listed but #40 is listed.
The part number is:
74851-ST8-A11 (#40 on diagram)
AcuraPartsOnline


Part # summary:
74851-S01-A01 6th civic (coupe/sedan, all years)
74851-S5A-A02 7th civic
74851-S84-A41 6th accord (2001 EX) automatic with release
74851-S84-A11 6th accord (2001 VP) manual with release
74851-S30-003 6th accord (1998 DX) manual
74851-S84-A21 6th accord (1998 EX) automatic
74851-SV1-003 5th accord
74851-S2A-003 s2000
74851-SM4-003 4th prelude
74851-S30-003 5th Prelude
74851-SK8-023 Integra


So, has anyone successfully done this before? Can anyone shed insight/photos of above parts (minus the 6th gen civic and accord parts, I will post those shortly if people are interested)?


Here are the photos of what I have so far:

Stock latch (74851-S01-A01) on my trunk (looking towards rear of car if the trunk is closed) You can see the rubber cover has been removed, and this shows the mechanism and the trunk-light switch connection.


Here is where the other end of the lock-rod connects with the keyswitch in the trunk.
If I fail at finding a easy solution to get the actuator onto the latch itself, it would be possible to add the actuator somewhere on this and push on the lockrod, but this would not be as strong a design due to relying on more parts to work.


6th Gen accord latch from a 2001 EX (74851-S84-A41) with the rubber cover removed to show the latch mechanism


Here is a close-up of the workings of the latch mechanism with the actuator and emergency escape lever removed. You can see the mounting holes are different, and if you compare the latches side-by-side it is easy to see that the lock rod lever (gold piece) is about .5 inches closer to the striker position on this latch than on the stock civic latch. This makes it impossible to install properly without first cutting the trunk, which I want to avoid. Also, I believe the accord striker has a larger diameter than the civic striker, since the hole in the catch is larger.


Here are the 2 rubber covers for the latches. Accord on left, Civic on right


Here is the accord actuator removed from the latch assembly. The above arm of the lever is the emergency escape, the left arm is what the trunk release cable (from next to the driver seat) attaches to, and the bottom arm of the lever presses on the latch to release the catch.

Canadian Acura EL 1.6 Sedan has a remote-operated trunk. (Surprised you didn't figure this out on your own, given the amount of research you did! ) In fact, it has no key hole at all. If you didn't know (but you should... ) the EL is an Acura-badged up-market version of the Civic, released only in Canada (and Japan). So, if a 6th Gen Sedan latch fits the Coupe (it should), then there's a very, very good chance the EL one will mount in the Coupe. Heading to the junkyard tomorrow, I can pick you up one.... PM is key.

redneckvtek

Thanks for the response.

Sedan Latch is the same P/N as the coupe for all trims and year models 96-00

Only thing that worries me is what you said about it having no keyhole at all. This would theoretically mean that they left out the lockrod attachment for the key on the trunk (see my 2nd picture)

PM sent anyways, I would be interested in getting that latch off of you if you find one. Would love to see pictures at a minimum, just to fully understand this situation.

EDIT: having trouble finding a place online that sells parts from CA. I would love to find the parts breakdown like majestic has for US cars. Here is a pic I found in the FSM for the EL. Remarkably, I had a much easier time getting the EL FSM from online than I had finding the civic or accord FSM.



From first glance, the rubber boot (or condom, lol) that covers the latch looks identical to the one i pulled off. Looks like it mounts the same way as well. Not sure, but it does look like there is a additional cutout in the trunk for the actuator though, so it might not be plug-and-play like us civic guys would want.

Yes, it might be all-electric, with no way to accommodate a lock rod. That's not terrible, though - if you still wanted to use a key you could adapt a switch from a different Honda/Acura that activates the opener electrically. Do the Integras do this, or does it just have an electric lock on the trunk exclusively for lock/unlock (not to pop them open)? Also not sure if this would have been a feature on the 3dr, 4dr, or both. TBH, I don't think they do ... though possibly you could adapt the mechanism that does this type of thing from the Integra's door latch.

Here is another pic of the EL's latch.



This shows HOW Honda adapted the latch to work electrically, and WHY it doesnt have a key cylinder.

It seems that the actuator just pulls on the same lever that the key cylinder's lock rod attaches to. Seems easy enough to just daisy chain them together with a double-lock-rod setup. I checked, and the lock rod moves freely on the inside of the trunk even without the key in the lock.

It looks like it may fit into the trunk without cutting from this pic, depends on how the actuator attaches. A actual photo of the underside of a EL trunklid would let us know for sure.

I would wager that the EL's trunk latch has the same P/N as the civics latches, 74851-S01-A01, but I woln't know for sure until I can find a online source for them or call a honda parts dealer. Unfortunately, its 8pm so even a west coast dealer in Canada is closed by now I would assume.


EDIT: got ahold of Burrard Acura in Vancouver. Parts guy was nice enough to look it up after I explained my situation. Gave me a P/N of 74850-F52-A01, which is the whole assembly. His system didn't break it down any further, or I couldn't effectively explain exactly what I needed. Anyways, that number doesn't really help. part was cheap though, and they were willing to ship.

Pictures of a EL trunklid. There is a extra cut-out for the actuator as far as I can see. No idea how difficult it would be to cut it for a civic, but pretty much throws out the idea of a plug-and-play swap unless one got the whole EL trunklid/lights/ect assembly

I'll be at a junkyard tomorrow. Plenty of ELs there. I'll take some pics and remove it, incl. a pigtail. Can't be more than $20 for it.

You can't get the whole trunk lid because the coupe trunk won't fit a sedan AFAIK.

E.

PS. We're still in the dark ages when it comes to getting parts online for Acuras here in Canada.

I would be interested in getting an electric latch for my 5th coupe, but I think thats a pipe dream from what I can see.

Hard to say without some research, the fifth gen latch is entirely different.

redneckvtek

S2000 latch from a 2006 s2000 (AP2)

I couldnt find a part number on the latch, but it looks identical to the 6g accord latch from 2001 model.

Either way, it prooves its not a viable choice for 6g civic owners.

deschlong, did you have any luck finding or photographing the EL setup?

THanks

Pics, as requested, of Acura EL 1.6 trunk latch. Vehicle was a year 1999 or 2000.

redneckvtek

Thanks for your time and effort to upload those pictures deschlong!

Here is a similar pic of my trunk, a 96 coupe trunk.


There is a extra giant cutout on the left on the EL trunk that the coupe trunks do not have. I am unsure if the sedan trunk's have this at this time.

This proves for sure that the EL latch is not a drop in retrofit for a OEM automatic trunk release.

At this point, I am thinking of trying the DEI 524N actuator. It is a plastic unit that is only $15 or so. This should keep the weight light enough to not affect the trunk springs but still hopefully have enough power to actuate the lid. I am going to attempt to make a bracket that is easy to use to attach this to the trunklid.

I think aftermarket is your best bet.

Some day I'll test fit an EL trunk latch into a 6G Coupe and Sedan while I'm at the junkyard and post back.

Sedan trunk is the same. Aftermarket it is.
