T31 Reverse light switch on Automatic I have a 2010 T31 and am frustrated trying to fix the reverse lights. Fuse was ok and replaced with a new one. Bulbs both OK. Trailer socket has a black wire connected to pin 2 on the seven pin trailer socket but this does not connect to the reversing lights??? might never have been connected as my trailers have never had reversing lights.
Where is the reverse light switch mounted on the six speed automatic diesel?
Is the wiring a simple fuse to switch to lights in parallel?
