gammite Posted December 30, 2012 Report Share Posted December 30, 2012 I put a 3.1 turbo motor out of a 89 TGP into my 91 Cutlass convertible. I am looking for the pinout for the C100 firewall connector for a 91 Cutlass Supreme. The car runs but there are a few minor electronic issues I am working to correct. I think they are post ECM but want to make sure. Does anyone know where I can get the pinout information? Quote Link to comment Share on other sites More sharing options...
intern8tion9l Posted January 1, 2013 Report Share Posted January 1, 2013 Im pretty sure they are the same, the differences lie at the ECM and they are few(I did the swap into an 89 cutlass). What problems are you having? Quote Link to comment Share on other sites More sharing options...
gammite Posted January 1, 2013 Author Report Share Posted January 1, 2013 I had to hard wire my cooling fans and do a work around for the A/C because I was not getting the high pressure input. My instrument cluster has a few second delay before power is fully gone. I will work through the inputs from the ECM to locate my problem. Thanks for your help.
