I chopped up the harness in my 88 civic for a MPFI swap. Now i'm going to sell the car because I bought a 91 Hatch.
The harness was already out of the 91 so I decided to just put that in the 88 so i could use the MPFI harness in the 91.

It appears there are some wiring differenced between the years though, Does anyone know if the 91 harness can be used in the 88 with switching some pins?
Which pins?

thanks

 

What models are the cars... si, dx, and hf are all different in the harnesses, and in most cases the 88 is the odball. Please be more specific

 

sorry, i posted that quick before work

the 88 is a DX and the 91 is an STD

 

with some searching (i know i should have done this before) i found that a big difference is the eacv 12v wire is moved to another harness. I think i can fix that easy enough.

Is there anything different with the top dead center sensor?
