I am installing a 3.4 V6 out of a 95 Firebird into a Geo Tracker. I am converting the original transmission to 4WD duty. What I would like to do is install a switch I can use when in 4WD low, similar to the performance mode switch in cars of that era, that changes the shift points of the transmission so it doesnt just stay in low gear the whole time. I am using tunercat to tune it, when I look at the available shift tables in the tune I do see options. I see shift tables for Normal mode, Traction control mode, Hot mode, and cruise mode. Does anyone know if there is a wire in the pinout I can install that I can use to activate one of these modes? There is no performance mode listed, and no wire for it in the pinout, but there are lots of empty holes. It is a flash tune PCM that uses 3 connectors, clear, blue, and black. It is listed as service number 16184737 BNPM. Thanks, Roy
