I am doing a '96 B18 GSR/5-speed swap into my '93 Civic hatch, and have come across a couple of issues.

First of all, can anyone tell me where to find pinouts for the engine and chassis harnesses? I have found that I have an extra connector on the stock GSR engine harness I am using that does not plug in anywhere on the chassis harness. I want pinouts so I know where to cut/solder/modify the wiring, and need to know if there's an easier way to do this. I've looked at the VTEC walkthroughs here and none of them mention this problem.

Also, I was given an OBD1 H22a ECU with this motor and was told that it would work fine. Is this true, or do I need a P75/chipped ECU?

Any help or links would be appreciated, thanks for any contribution!

 

Quick edit: The engine harness is an OBDII, as is the engine ('96 GSR B18C1).

The ECU and the Chassis Harness are OBDI.

 

Bump!

 

Okay, I've done some research and found that what I need to do is somehow wire my OBD2 engine/engine harness to my OBD1 ECU/ECU harness. Are there any kits for this, or will I have to do it all myself?

F**k yes! Thank you! I searched all over!

 

I woulduse the 96 harness and add the wires for vtec, knock, and IABs from the shocl tower to the ecu and get a obd 1 gsr ecu or a P28 and new manifold. the extra wire is prolly for abs.

no need to solider, only re-pin a couple wires

search the answers are already here somewhere.
