Like the topic says I needed a motor for my 90 si and I went and bought a 88 si. well most of the connecters worked except for the 2 by the injector resistor box. can any one help me with a wiring diagram? and I dont have the 90 wiring harness anymore. thanks guys and girls. can some one please put up a diagram of the harness from the block and right of it? for both years please.

cmon help

 

somebody

 

most people use stock harness since it easier

 

my stock one is gone. and I cant find another

 

need a diagram

 

wow.

 

damn thats the only response?

 

bump

 

why did the plugs not fit? I have a 91 harness in my 89. So far the only problem I had was that the reverse light was not where the it was suppose to be so I had to rewire it. I believe I have a 90 crx si factory manual at work I'll see if I can do anything else.

 

I hope this helps. I have an 89 Si that Im finishing up and used a 88 Si Harness ( cars not done yet but heres what ive been told )

In your engine harnessm besides all other wires, it will have a Red/yel wire next to Red/white wire. The 6-wire plug next to the round plug will have Blue/yellow next to Blue/green wires. These two pairs will need to be swapped over:

Blue/yell swaps places with Red/yellow
Blue/green swaps places with Red/white.

You'll see on the car side of the plugs, there will be wiires of the matching colors, so you'll be able to verify it.</TD></TR></TABLE>

88 Si has a square 6 pin connector - 89-91 Si has a round 8 pin connector - this is because the 89-91 Si had a Fast Idle Control Valve and 88 Si didn't - thus the extra wires

 

I'll have a 90 crx si harness I can sell you in a few days.. would you like it?

 

well on the drivers side strut tower when I throw away the dark blue wire what dod I do with the black wire with yellow stripes? throw it away?

 

yes, sort of - black with yellow stripe is "hot" with ignition on - just make sure it isn't grounding out on anything

 

thanks guys
