Torque convertor lock up switch
 

Alright i did this to my truck last night useing the tstproducts link. I spliced into the orang/black tracer like it says then run to toggle an grounded it. When i flip the switch Wait to start light comes on an noithing more happens. What did i do wrong? Did the jumper in the fuse box. DO i need to go under the truck And splice into the number 7 pin wire on the trans? Thanks guys.

There are 2 similar colored wires on the harness there. Make positive sure you spliced the right one. The wire is in one of the 4 corners of that connector, i forget which one, but make sure the one you spliced is in one of the corners and not in the middle or something.

Good luck, and remember to flip that switch off when ur coming to a stop... :nope:

still no luck

im getting ready to do this too.. i heard its worth it

Its worth it... The only negative is it throws the code for the tranny solenoid saying there is a disconnect... But it wont set off the check engine light, it just gets stored in the CPU. Kinda confuses things when ur trying to figure out transmission problems like im having right now. But otherwise its nice for highway driving.
