i have a 89 crx that im building, and the harness provided with the car is an si harness, but a couple plugs are missing, and i dont feel like finding a parts harness and piecemealing it back together. i was just wondering if anyone here might know a shop or boneyard that might be able to locate either an si harness r possibly 90-91 integra gsr or xsi harness. thanks

 

You have the harness that is needed. Just get the adapter harness which can sold, or add the supplement wires yourself.

There was no 90-91 GSR. GSR was not introduced until 92.
The XSI or any other JDM wiring is not something you want to try to get to work on a US car.

Use the US harness, either purchase the supplement harness or do it yourself.

 

i'm afraid you're not going to go very far in build if you don't want to add a couple vtec wires to your ecu. if you're converting to odb1 your jumper harness should already have the wires in the pinout spots., all you'd have to do is attach them to the vtec solenoid.

 

you could also have hasport build you one. best regards
