The rest of the diagnostic page !

That's why I suggested a 'conversation' with maybe the fabricator. Marc is also a good choice! If you don't have the 'switch' and the IGN power i'd think you have immediate issues.

Do you have the '91 ECM 'pin-outs' to confirm what you have for a harness to the ECM?
