To make sure we're talking about the same light set-up, here's a picture of what I received from TJM, along with the installation instructions. As you can see, there is a 3-wire pigtail that plugs into the light fixture. The pigtail has a green wire that is associated with the clear fog light, a black ground wire, and a red wire that is associated with the amber turn signal/parking light.
In my opinion, the green wire would be connected to the positive factory fog light wire, and the black would be connected to the chassis as a common ground. That leaves the ONE red wire to connect to the factory turn signal/parking positive light wiring. Unfortunately, it can only be connected to ONE of the factory wires (EITHER the turn signal wire OR the parking light wire), leaving one of those functions inoperative.
Comparing the provided light setup with the installation instructions, it seems that there should be two separate harnesses: one 3-wire harness (white & brown & yellow, as described in the instructions) for the amber turn signal/parking light, and one 2-wire harness for the clear fog light. Of course, the 2 harnesses could be combined into one 4-wire harness if there was a common ground wire. In any case, the turn signal/parking light requires 3 wires in order to function properly.
Thus, I still contend that something is amiss...if anyone else has done the install, your input is welcome! Also,
@Phil Damon, if you can comment on this it would be helpful.
