When I did mine there are a number of wires with the same color. I used a CT to measure current through the wires to identify the correct pair. This way I did not have to pierce each one with a meter to confirm. Not everyone will have a tool like this though. I am just saying you will want to confirm before going to the trouble of splicing into a pair.
This mod is fricken awesome . No more wondering if I locked the tail gate.
