Most of the way through a towbar installation which has been pretty straightforward, until trying to get the wiring completed behind the dashboard.

I can get the bcm module removed and if I could get the connectors further down then swapping the required pins doesn't concern me, I just can't get at them or even see what I'm doing!

Any tips or suggestions to get any better access to them?

 

Well, to answer my own question there is no easy way, but got it done. Door wide open and contortion in the footwell and everything hooked up correctly!
