Thanks twinspoppa. I didn't think of going to realoem so appreciate that. I will hunt in there. My end of the cable in the picture is female and the realoem diagram shows male. not sure if thats just a drawing error, but none theless your point is right I should look in there to see.

MTX5 I agree. From the sound of tailgate noise this definetly isn't it, and yes I have check the write ups and I am following those, this just came up during the noise investigation.

X5 meister, not sure why i would do that. If the cable is connected somewhere, where its even harder to get to than i have just created another problem.

Appreciate the help
