Im helping a friend swap an obd1 92 integra ls b18a motor with a p74 ecu into a 90 civic std. which i believe had a pm4 ecu. Im converting the car to obd1 and the swap is completely done except I need to wire in the ecu and I cannot find any reliable ecu pinouts that correspond with either of these ecus. Ive already tried searching and found a few pinouts but they are not quite what I need. I also remember seeing other pinouts in the past that I could not find by searching. If you guys could please help me out by posting whatever non-obd or obd1 ecu pinouts you have it would help me out a lot!!! Thanks!!!

Good luck. I dunno if those will help, but they've helped me tremendously when I was doing my swap.

 

Both of those are obd2 ecus, thanks anyways though! Anyone else have any ecu pinouts that may work???

 

Anyone?

 

here are some for an PR3 ecu.

You have to convert your to MPFI first before you can go any further.

 

The car has been converted, the engine is in and everything is wired under the hood. The extra wires for the injectors, distributor and any other wires that were not present in the civic harnes have been run all the way to the ecu. All I need is some reliable pinouts so we can plug the ecu in and its done. I have found a few incomplete pinouts for the civic ecu that could get me started but I cannot find anything for the 92 integra ls ecu.
