Towbar electrics

Post by bendeus » Wed Mar 18, 2009 12:58 am

Hi all,

Just fitted my towbar (to pull a trailer) last weekend and now with a shudder am about to attempt the wiring. I'm not very competent with electrics but in this instance my poverty outweighs my ineptitude, so am determined to carry on solo without an auto electrician.

Having studied the factsheet in the members' area, I still have the following queries if there's anyone out there who can help me:

* Do I need to disconnect the fuses to isolate the relevant circuits and if so, where would I find the ones I'm after?
* Am I right in thinking that all the lights for a trailer light board can be connected up to the wiring loom in the n/s rear side panel save for the o/s indicator light?
* If so, what kind of wire will I need to connect the indicator wire from my seven core cable to the o/s indicator if I run it across the floor?
* Finally, the instructions on my audible sensor relay tell me 'Do not cut the wires to vehicle indicator lamps'. If I can't cut them, how on earth am I supposed to wire them in to the core cable??

Any help would be very, very gratefully received :)

Hi,

Haven't done this myself but can give you some general help.

It's always a good idea to remove power when doing any electrical work, simplest way to do this is disconnect the battery.
Before you do this, check to be sure you have your radio security code if it has one.

With regard to tapping into wires, the easy way is to use scotchlock connectors. they fit around the existing cable and tap into it joining in the new wire. However there is a cost as these tend to be unreliable over time. You are better to invest it a good crimping kit and use the appropriate connectors, or solder, both ways mean you have to cut and rejoin the existing wires.

As to what wires to join, without a wiring diagram it's hard for me to say. If you are in doubt or have a concern it maybe worth seeking the help of an auto electrician or a good place like Wheelquick etc depending on where you live to finish the last bit off.

Hope this helps.

This isn't difficult, but I would warn aganist Scothlocks fo 2 reasons:

The Bongo wires are very thin, so you don't always get an electrical connection, and

Used outside the damp will get in and cause problems.

Warm welcome. :D

Scotchlocks cut the insulation and also bite into the plies of the wire, even used inside they ruin the integrity of the wire and are just trouble waiting to happen
