Gordon, I havent even noticed when fitting trailer brakes with our test board:eek:, just very busy, I have yet to also tow anything with a D4, so next time i go to work i will have a quick gander...HHMmmm.
I would assume it will, but....
$295 + shipping.
Just a plug & play module.
If u do want one let me know & i will organise one to you.
I will be back at work on Tues. 03 9684 1021 direct.
Cheers.
p.s. Mowog can u answer Gordon's question above?
