I've put a B16a SIR2 in my 91 Hatch and I've got a wire conversion for the ECU. The conversion harness does not provide jumping for the Service Check Connector. What pins on the OBD1 ECU do I need to jump to get my CEL to display my error codes?
Normally, you would use the little jumper under the dash, but mines converted, so I need to know what to jump out of the ECU. Thanks

 

What conversion harness did you use? They usally come with two wires tat arent used and you can twist them together

 

I got a generic conversion without instuctions, so I need to know what Pins on the ECU I need to jump. I know about the Service Check Connector. I just didn't want start sticking in everything or applying voltage to it, ECUs arn't cheap to replace

 

Ground pin D4 to check the codes.

 

Thanks for the Info! I'll check it when I get my engine back in.
