gtp237 Posted October 2, 2012 Report Posted October 2, 2012 Hey I am putting a 95 3.1 in a 96 grand prix. I hit a few wiring snags.. First one is this plug. It goes right where the coolant temp sensor sits but the plug is totally different. Next one is this ORANGE connector, it sits near the egr. Theresa a couple other issues but lets start there. Quote
RobertISaar Posted October 2, 2012 Report Posted October 2, 2012 coolant temp sensor: 96 engines used a single 3 wire coolant temp sensor, 95 and earlier used a 2 wire sensor for the ECM and a 1 wire sender for the dash. either get the one to match your harness or change the harness connector out for the one on the engine.

gtp237 Posted October 2, 2012 Author Report Posted October 2, 2012 Alright thanks, that makes a lot of sense. Do have any ideas on the orange connector? Quote
RobertISaar Posted October 2, 2012 Report Posted October 2, 2012 what color of wires are going into it? Quote
carkhz316 Posted October 2, 2012 Report Posted October 2, 2012 Just looking at the picture, the orange weather pack connector looks like it plugs into the ICM. There is a open plugin on the ICM that is begging for something to be plugged into it. Quote
emptytank Posted November 14, 2012 Report Posted November 14, 2012 95 was a goofy year, kinda the switch over year from od1 to obd2, sorry i cant help more Quote
19Cutlass94 Posted November 14, 2012 Report Posted November 14, 2012 That orange connector looks like it goes into the alternator. But if its around the EGR, check the O2 sensor. Quote
