I put a "t" like 8" before the tranny cooler on the hot side.. From there I put the bulb that I got with the gauge kit and I run the SIGNAL wire from there all the way to the gauge.. I weld also a ground wire to the Cooper "T" and the chassis.. Also another ground wire from the gauge to the battery and the + wire from the battery to the gauge too.. I do have to say that the signal wire was a bit to short and I have to add an extra 15" of wire, can that be an issue to send the signal messed up?
