I have a 94 civic VX and I did a b-series swap into it.. I used a 94 GSR engine harness and plugged it up to my stock 94 civic vx main harness..

For some reason the iacv isnt working.. It worked fine on my other setup(89' crx) but not in this one.. I know the iacv works since I tested it.. Is there any special re-pinning I have to do or anything when using these 2 harnesses.. I am going to trace the wires back to the ecu to make sure they are correct but I just wanted to see if anyone knows off the top of their head what the problem might be..

Everything else with the car works great except for this.. Also does anyone have a diagram of what plugs are what on the 94 gsr harness.. All my experence is with 88-91's and this is my first 92+ car..

 

Also what color wires go to the iacv valve and what color wires go to the evap purge valve?

 

I got the iacv working, the plug for it was hidden underneath the manifold.. Now I have 2 extra plugs that are the same as the iacv...

1. intake air temp
2. iacv
3. EVAP noid
4. ?????????

Whats the 4th one?

Since this is a GSR engine harness could it be the IAB?
