Just fitted the wesfalia towbar on the wife's 500C twin-air - went a lot easier than the instructions indicated as it is NOT necessary to remove the bumper - just undo the two screws underneath to slide the bar through. And there isn't any mucking around with the exhaust and heat shields as the twin-air final silencer box is so small compared to the others.
Electrics are a bit more of a problem - the wiring loom colours don't seem to match anything shown in other threads, but I think they are:
left:
1 - Blue+white - indicator
2 - Grey+green - reverse
3 - Black - ground
4 - Green+white - brake
5 - Yellow+red - sidelight
right:
1 - Yellow+black - sidelight
2 - Green+yellow - brake
3 - Black - ground
4 - Brown+grey - fog
5 - Blue+black - indicator
If someone could verify these, I'd be very grateful.
Also, the handbook shows that Fuse F09 under the bonnet is labeled "trailer" - there isn't a fuse in the slot, but does this mean that there is a feed from the fuse box into the boot area already? The (westfalia) instructions tell me to add a new wire and in-line fuse holder onto the battery and run a new wire all the way through the passenger compartment to the boot to power the by-pass relay box, which is a bit of a palaver and a lot of wasted effort if I subsequently find there is already a feed hidden in the loom somewhere! So does someone have a wiring diagram for the 500c twinair that they could check this for me?
Thanks.
del - somewhere in somerset.
