I having problems with the swap. My car is a 91 RS, and I put in a 355 with a MAF TPI. First of all, the car will not start at all, won't turn over. NOthing. Secondly, SOmething is screwed up with the wiring because if I turn my dimmer switch one direction, the tach lights up, but if I turn it the other direction, the speedo lights up. The radio, windows, etc., seem to work fine. Finally, I don' know how to hook up the VSS to the TPI wiring harness. The harness I have is the one sent with the TPI, so I think that it is GM. Can anyone help?? PLEASE??!!??
