Hey guys. I have a 89 crx si and we dropped a ZC DOHC in it. i was just wondering what all the wiring modification you have to do to make the si harness compatible with the ZC.

 

On the Si distributor there is a 7 wire plug on the wiring harness, but only 5 plug connector on the ZC distributor, and there is a sensor on the exhaust cam, which is the cam angle sensor, that has no where to plug into. So this is what you do:

1.The Civic wiring on the distributor has an 8 pin connector and a 2 pin connector. The 2 pin connector from the Civic wiring harness will connect to the ZC disributor.

2. Pop out the 8 pin connector off the Civic engine wiring harness

3.This will expose 7 wires.

White/thin

White/thin

Orange/Blue stripe

White/Blue stripe

Blue/Yellow stripe

Blue/Green stripe

4. Pop the pins out of the square ZC plug, This will expose 5 wires.

White/Thick

White/Thin

Orange

Orange/Blue stripe

White/Blue stripe

5.Now you simply place the five pins in the square harness and get rid of the round Civic one.

6.You now have two extra wires which are Blue/Yellow and Blue/Green

7. These two wires go to the green plug on the crank angle sensor which comes off the exhaust cam. you need to splice the wires, but make sure to use bullet connectors. If you dont you will lose to much power through the connection and the computer may throw a code.

 

This info is also in the FAQ version 2.0 thread

 

maybe the attached will help

 

thats what everyone has been telling me but my problem is i got a dizzy for the 89 intergra and the colors dont match up. from the car side the wires are : thin white, orange, thick white, white/blue, orange/blue, blue/yellow, and blue. ( blue/yellow and blue to sepeate sensor im guessing) From the dizzy the wires are: White, orange, yellow/green, blue, blue/yellow
