using a test light at the vehicle-side plug in the car, test the various functions.
If they don't work, you have a problem up the line (you have already tried 2 modules)
If they do work (and they should), you have a pblm with the harness between vehicle-side plug and trailer plug.

The images with my X5 and incandescent trailer, was with the OEM connected nothing else. And only mounted in the stock position/location.
(Only thing I made was the trailer plug to trailer connector. used OEM plug and pins that connect to vehicle plug, and used thicker wires.)
I had tested the Vehicle side plug wires with a voltmeter, I can read the bulb check pulsing on the voltmeter, but no turn/brake solid signal when initiated.
I will swap back the 3 pink terminals to the OEM setup, use a test light instead of the voltmeter. To verify I have a signal other than the pulses.
And post what I can back on this forum.
