bebop138 Posted March 15, 2006 Share Posted March 15, 2006 On th SP400 what is the wiring on the plug--the inside of the tranny--are the wires color coded. Which wire goes to the verticle spade and the horizontal spade?? Thanks 52er!! Link to comment Share on other sites More sharing options...
NTX5467 Posted March 17, 2006 Share Posted March 17, 2006 The wires will be color coded. If you can get a Buick factory wiring schematic, it should detail which color wire goes to which terminal on the connector. I suspect they would all have the same color code--just a hunch.Be also aware that normal THM400s did use an electric kickdown mechanism, which also generates a 1-wire plug in the transmission case. One of the wires in your two wire situation might be for that function too.Just some thoughts,NTX5467 Link to comment Share on other sites More sharing options...
