Wiring towbar lights. Right or wrong?

mcneil

Not that I'm going to be doing a diy job, but someone who was going to do it at weekend suggested it.

What he suggested he does with new towbar is wire it into my back lights. I don't know much about cars or wiring but shouldn't the towbar have its own circuit from the fuse box? Would like to know this before I let the garage wire this in.

No just wired into the back lights is grand with a trailer module if your car has can bus wiring if not it doesnt need the module.

The correct way to piggy back off the rear lights is to use one of those modules regardless of the canbus status of car.

That was the additional load placed on the rear lights is miniscule and less likely to cause problems.

The main load positive to the module is then sourced from a robust source and an inline suitably rated fuse added

It means it does not take the power from the lights, it only uses the lights to tell the new module what needs to be activated. And then this one is the one giving the lights to the trailer.
If you connect the trailer lights to the car lights with nothing in between, you could overload it and burn the fuses, the lights, even the wiring. That is why the module should be used.

I got a a kit from pfjones in UK, it had the car and model specific wiring diagrams included
