K, I have a 91 si with a gsr swap, the CEL light has been coming on, and I don't know how to check the codes for it, it has a boomslang converter harness obd0 to obd1, the ecu is a chiped p28, the engine is obd1.

I just need to know how to check the codes. Thanks.
 
i may be wrong. but i believe there is a 2 pin plug near the bottom right of your glovebox. jump the connections with a paperclip or whatever, and the cel should flash on your instrument cluster giving you the codes.
 
On most ecu jumper harnesses you will have 2 wires usually Orange & blue for checking cel's but in this case Boomslang doesn't wire theirs up that way.

Heres what they have on their installation instructions:
Check Engine Light (CEL) codes can be checked by jumping your
vehicle’s factory 2-pin timing adjusting connector. This
connector is near the driver’s side shock tower on 1988-1989
vehicles and in the passenger side interior foot-well area on​
1990-1991 vehicles.
