Question:

Installed on 2013 Edge car works okay but when connected to MH no lights work at all on the Edge. I checked and I am getting power to the plug on the back of MH to the plug coming from wire harness. I noticed the 2012 you installed on has the turn signal red on my the turn signal is seprate and yellow. Help I am leaving on wednesday and I need this to work.

I think that you may not have the ground securely fastened to a clean metal surface. When you are testing with the circuit tester you are actually completing the circuit and that can make you believe all the wires are installed and attached properly.

A loose ground can cause any number of things including the problem you are seeing. Check out the attached video at the 10:17 mark and you can see how they attached the ground wire. You may find that takes care of the problem. When the system is installed, the turn signals are operated with the brake lights so the turn signals on your Edge that are amber will not function as they do when the car is not being towed.
