B18a wiring

I'm helping a friend put a B18a into his 88 CRX Si and we got the motor in but we haven't looked at the wiring yet. I'm pretty sure that we need to take the wiring harness out to the integra and put it in teh CRX. Anyone know what all you need to do to get the motor wired up ?

what year motor is the b18a? If its 90-91 its basically plug and play, but if its a 92-93 then youre gonna have to convert to obd1, or downgrade it to obd0, and extend a couple wires.

oh yeah, you use the stock crx harness, not the teg one

We ended up taking the harness out of the integra and just puting it into the CRX. It wasn't that big of a deal or anything.

is there anyway you can tell if you got a 90-91 b18a or a 92-93 b18a ?
