Title: Towbar wiring
Post by: The Barge Captain on 04 December 2007, 16:34:17
I need to fit a towbar to my facelift estate.  That's not a problem, however for the wiring, do i just scotchlok (yuck) into the existing loom / plug or should I invest in one of those fancy new multiplex systems?
If I go the old fashioned route, does anyone have a list of what to connect to? (12N only)

All advise gratefully received.

I wired up my facelift estate, cut off the plug (gave up with the dealers trying to sort out the right one) and wired it up with crimp connectors for all the lights except the brake light which i picked up from the nearside light cluster.

Neatest way is probably to find the towbar pre-wiring connector and either purchase a mating connector from VX or cut it off and solder join and heat shrink your wiring to the wires there. The colour codes in the linked article stand at the pre-wiring connector too.

You'll need to add an audible warning device for the indicators (or change the flasher unit and add a bulb to the instrument panel) and also bridge the two Black / Yellow wires in the socket for the brake light current sensing socket (like a relay socket which I found behind and to the left of the glove compartment).

There are a couple of threads in here on tow bar wiring. Might be worth a search.

The trailer check control was only about £16 and will keep a permanent checkon your brake lights.

Does this remove the necessity for linking the 2 black / yellows?

Yes! The link wire is a 'bodge' so that you don't have to fit the check control 'relay'. The hardest part for me was finding the base for it. Mine was above the driver's feet, but as Kevin says later cars have it behind the glove box.

What does the check control do once installed, out of interest?

Obviously it will alert you of a blown brake lamp on the trailer, but how does it know there's a trailer there in the first place?

Ahh, That's where you and I differ. If I don't know how it works it's no good. I'll probably end up taking it apart to figure out how it works, and afterwards it won't work any more anyway ::)

We're both exactly the same but  ..... different. If I can put a spanner to it I can fix it beyond repair ;D, but as I'm only a semi-skimmed spark/fitter I don't do electrickery. :y
