I dunno about wiring but i wanted to ask why u wasted ur money for an obd swap when both the engine and the car are the same obd...it shoulda plugged and played.

actually no there not a 91 dx is obd0 and the 92 b18a1 is obd1 tried to plug and play wouldnt work had to buy the harness

you should have bought an OBD0 distributor and ECU instead - it would have been all but pulg and play then (well, a MPFI conversion)... I have a 97 B18B in my CRX, runnning OBD0. Just add 90-91 teg distributor and stir gently.

There is not a standard way of making OBD0-OBD1 conversion harnesses. I've seen at least two different ways - main difference being how the rewiring of the distributor is handled. With your car being a DX, you really are in a world of pain because you need to do the MPFI conversion and the OBD0-OBD1 conversion at the same time.

Good luck. This is tougher than anything I've heard in this forum for a while.

If you don't already have a helms for your car and a 92 integra, get one now. You'll probably need both by the time all is said and done.
