How do i check for codes in my obd0 car after i've swapped to obd1, i know in obd1 cars there is already a connector that you have to jump, are there two pins on the ecu harness that i can jump after i've done the conversion to make the CEL flash my codes?

 

There's only one pin that you need to look for...If I remember right it's A13 (on the obd1 harness) that you jump to ground to flash out your codes on the dash. Most aftermarket adapter harnesses should have a wire coming off this pin, but not all of them may. Might want to search for the pin outs just to double check.

*Edit* A13 is for the MIL code light, D4 is for diagnostic...might want to try D4 instead, sorry.
