Hey guys, I bought a 89si hatch shell and I got this harness with it.

Im trying to figure out what each connector goes to. This is my first obd0 88-91 civic and Im not too familiar with these harnesses. Ive done around 50 obd1& obd2 civics but this is my first obd0.

Any help would be greatly appreciated. Thanks guys

 

They are honestly all the same. If you have done that many obd1 and obd2, it should be a piece of cake. Literally all the sensors are in the same spot on d and b series motors. With a few exceptions. Put it on the motor and you will see.

 

He is right. Aside from the distributor connections, which will become apparent with the rest connected, they are all the same. People use the factory harness with slight modifications (extensions) to run OBD2 GSR motors in here and OBD1 everything. It's easy. Just slap it on the motor, it all lines up.

 

alright Ill slap it on and see what I get. I can tell there isnt any wires or connectors for the reverse lights by just looking at it & that the one connector that looks like a plastic 90deg thats not factory?

 

That's really the best bet. Slap it on the motor and like 95% of it is 1st grader shape matching. The reverse light thing is weird to me... Should be there unless it was cut off. The 90 degree may be a strange aftermarket boot. What's the inside of the connector look like?

 

Correct the 90 degree plug isn't factory.
