How difficult is it to fit your own tow bar?
I'm fairly good at car DIY, i.e. wire in a new car radio/cass. How
difficult is wiring in tow bar electrics?
Any pointers to look out for
If you can fit your own radio/cassette, you'll be able to wire up a towbar.
I just did this job, and the 12N socket (black) for the caravan external
lights was simply a case of finding the right feeds and splicing in the
wires to the socket.
The 12S socket (white or grey) for running the fridge and charging the
caravan battery was a little more awkward, simply because you have to run
wires the length of the car, from the car battery all the way to the socket
on the towbar.Some folk run wires under the car, others feed through the
interior.The facilities you have to work with may influence your choice, I
ran the wires through the interior to a voltage-sensing split-charge relay
mounted in the boot.The hardest part was finding a way through the bulkhead
into the engine compartment.Look for blanking plates or grommets covering
where the pedals or steering column attach on LHD versions of your car. My
Citroen Xantia has a big grommet where the LHD steering column goes.
If your car has bulb failure sensors, or ABS brakes (ECU), you may need
additional components in your wiring to enable these to work properly with
your modified wiring. Wiring kits are available that include these.
The age of your caravan will dictate the details of your 12S wiring,
pre-1998 vans are wired differently to newer ones.
I found that buying a pre-wired socket kit saved time and I think it made
the job easier.
