Slightly off topic

Slightly off topic I know but not really sure what NG to use, perhaps someone can answer my questions or point me to the correct / best NG to ask.

I have been trying to find a website that tells you how to wire the electrics for the towbar on the car.

also,

I want to put a reversing alarm on the car. Easy enough, connect one side to earth and the other to the reversing lights, but, I want it not to sound when the side lights are on.

Any ideas greatfully appreciated.

You would need to need to wire your alarm through the normally closed contacts of a relay whose coil is connected to the side light circuit - so that the contacts open and disable the alarm when the side lights are on.

Simple, wire the alarm througha NC relay and connect the coil to the side light circuit. Ligths on = relay open. As for wiring the electrics to the socket, just do what everyone else does and make it up, every vehicle I've had has had a different arrangement! Or Google.

Thanks chaps for the advice. I haven't done any electronics now for about 6 years and I just could not seem to fathem the wiring for reversing alarm out. Need to take a few Aspirins and have a lay down I think...!

Alarms are available with an extra connection that prevents the alarm sounding when the lights are on. eg:

With a modern car I would suggest at least finding out if the car manufacturer has a towing electrics kit, bearing in mind the need to uprate/alter the indicator flasher and provide an additonal warning light. (Based on my experience with a recent VW)
