Robby1870 Posted September 22, 2003 Report Share Posted September 22, 2003 Shouldnt I be able to run a switch to the power wire for the TCC that is in the plug on the front of the tranny? I just dont know which wire is the TCC power wire. The Chiltons doesnt tell what wire is what. If any one knows, lemme know Robby Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted September 22, 2003 Report Share Posted September 22, 2003 i think it's black/tan. can someone verify that? sorry i'm not quite sure....i'm going to go dig out my '90 GP wiring diagrams.... joshua Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted September 22, 2003 Report Share Posted September 22, 2003 okeedokee. looks like there is 5 wires in that plug: purple - stop light switch tan/black - TCC or upshift light blue - 4th gear input white - 2nd gear input dark green - 3rd gear input so i guess that means the TQ converter can lockup in every gear except Reverse and 1st? btw, i looked in my '91 Cutlass diagrams and it was the same as the '90 GP diagrams. hth joshua Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted September 22, 2003 Author Report Share Posted September 22, 2003 Yeah that helps, but the TC only locks up in 3rd and 4th......... Robby Quote Link to comment Share on other sites More sharing options...
