I bought a 90 crx si with a tucked harness. I did an obd1 b16 swap. How do i get the codes? Wires have been moved around and tucked. Can i find the pin out chart and ground the scs pin on the ecu? Thanks for the help.

 

Which jumper harness did you use for the ecu?

 

car already had it, so i am not sure.

 

I found the factory plug I needed. It was in the correct place on passenger side , but tape up so I couldnt see the plug.
