I've looked at several different websites and 5 different posts on HT here for this info, but I keep getting info that I'm unsure of. Does anybody have the diagrams for those 2 plugs?

 

TomCat probably has them. Send him a PM.

 

Will do.

 

I replied to your PM. There isn't any 1 diagram for the shock tower plugs, it's spread throughout the ETM.

Right Tower
C124	Tower Harness	2 pin Grey	(Power)
C125	Engine Harness	8 pin Grey	Junction
C126	Tower Harness	14 pin Grey

The C125 Junction if I recall is a power junction all pins connect to each other. Also Canada has Daytime running lights, I'm assuming you do not being in the states.

I did have some of the C126 connector mapped out in my spread sheet.

Can you tell me which two connectors you are after? C126, C125 and/or C124?

 

I'm fleshing out C126. I will edit this post with the rest of it once I'm done. I am heading out for dinner and will continue working on it once I get back. @Freedo_Civegra all done and uploaded. hope this helps.

C126 spans over 1/2 of the ETM. Could be why I sort of glazed over it beyond the PGM-FI sections that were more model specific. Also of note, C302 is the 20 pin grey connector under the drivers side dash that is way up by the firewall right beside the C301 brown 20 pin connector. It's not the most fun to unhook from it's bracket.

Here is what I have at the moment:

C126-3	EVAP	Red - Red/Blk (Coupe-Red)	C117-2 Red EVAP Valve to C302-5 Red/Blk (Coupe-Red) Cabin Harness to ECU
C126-4	IACV	Blu/Yel - Grn/White	C115-1 Blu/Yel IACV to C302-2 Grn/Wht Cabin Harness to ECU
C126-5	VSS	Blk/Yel - Yel/Blu	C302-3 Blk/Yel Cabin Harness (From Fuse Box) to C112-2 Yel/Blu VSS
C126-6	VSS	Yel/Blu - Yel/Wht	C302-8 Yel/Blu Cabin Harness (From ECU B10 or Cruise Control Unit) to C112-3 Yel/Wht VSS

C126-14-M	Backup Light Switch	Yel	C302-1 Yel Cabin Harness (Fusebox) to C110-2 Yel-Grn/Blk Manual Transmission backup light switch

 

Dang, Tom! I feel like I oughta pay you something for that! THANK YOU!!!

 

Looking at C126, positions 13 and 14 are for reverse lights on MT harnesses?



And 3 of the wires on this connector are different colors at positions 3 (PNK/BLU), 4 (BLK/BLU), and 6 (ORG). It shouldn't matter if they all go where they should, but it's just noteworthy that there can be differences in colors sometimes.

 

Keep in mind, I only have the 93 ETM. There might be minute differences in the years as there was an ETM put out for every year if I recall. I think @deschlong might have indicated a couple of wiring differences between the years of 5th gen once or twice.

Of note, 126, 3 4 and 6 are trim specific in 93. What is above is the non VX. On the VX it might be a little different.

And yeah, 13 and 14 I believe are back up lights on the manual transmission. I remember tripping out a little bit on that as plug that normally plugs into the automatic transmission is used on the reverse plug of the manual transmission.

Oh, I see where I missed and mixed pages. So Automatic C110-1 and C110-2 goes to C126-13 and C126-14 respectively and is solely the lock-up solenoid. Yellow for 14 and Grn/Blk for 13. On the manual it goes to the the back-up light switch on the transmission. At the transmission side both wires are grn/blk while the harness side reverts to the yel for 126-14 and stays grn/blk for 126-13.

 

Are you sure that's not Pnk/Blk?

I almost wonder if you have C103 there. It is on the other shock tower and has a couple of Oranges but they are striped. I wonder if the white might have faded to look like a solid orange.

Or maybe it's a franken plug made by someone else at one time? C103 is missing a couple of wires and typically has terminator plugs for those two spots.

I guess Honda could have changed the wire colors down the road but I am not so sure.

 

Everything looks to be right on my connectors here. You really have a wealth of information. Thank you for sharing.

what's a bit consoling is that a 92-95 civic engine harness is exchangeable with the 94-95 (and maybe 96-00?) Integra, so that's all good. I omitted the 01 because I think somebody, maybe on this thread, said something about them being different. I may be mistaken.

 

I updated the table to fix the error you pointed out.

I was under the impression 94-97 integra was the golden range but not sure either lol.

 

I know for a 100% this came off the driver side of a 95 gsr because it was mine! Lol

I replaced the harness because some wack job had "repaired" tons of wires by twisting them up and taping them together as a permanent solution, and I said screw it and got a good harness.

Been cutting off the connectors and tossing them into a box. All wires seemed to go to all the right places.

Looking at the integra diagrams in my (wait for it)....

Haynes manual....

The vss has an orange wire which goes to 126-6.

The PNK/BLU wire at 126-3 went to the IAB on the B18C1 manifold and BLK/BLU at 126-4 went to the IACV. Mystery solved. Lol

Everyone else, please don't roast me too bad on using this Haynes manual. I did a J-swap with it and the Honda Accord manual and without asking questions on the internet. Lol

 

No one should roast you for using a Haynes Manual. The reason I say that is, it's still better than many who don't use ANY manual.

Haynes isn't bad just not as in depth as the Helm's manual. But even the Helm's manual has errors. So really at the end of the day, they are both helpful tools, just one is a little more helpful than the other, that's all.

 

I need the connecters mapped out for "C125 Engine Harness 8 pin Grey Junction". I have a DA Integra obd1 and I'm trying to put a DC Integra LS engine harness in. The c126 plug is the same but there's a different plug [9 pin] in place of C125 on the right side, also has a 4 pin plug that I think is for injector signal that has no where to go on the frame. I was just going to wire the C125 plug in place of the 9 pin plug on the DC harness but I need to know what all the pins are and if that would even be possible.
