Wireing a towbar

should do as the sub frame is the same
check with a tow bar fitting shop and remember you will need a modification plate attached when the tow bar is fitted
If you cannot be bothered with the mod plate then in the event of an accident your insurance is wiped and you could be charger under state laws
have the tow bar shop fit the unit , get the plate attached and get the wiring loom for the plug from them as well

trailer harness is connected directly to the rear lights
A relay will only operate one circuit and there are 5 or more separate circuits for a tow bar

If you have a wired tow hitch on your car you will need to mate this to the wiring harness on the tow bar. If the two wired units do not match then you will either need an adapter or will need to rewire the tow dolly or the car. If the car doesn't have a tow light unit installed you will need to install one that will mate to the tow bar light unit.

I hope this helps - please rate me

could be a relay or maybe even a cable break, hope it is the former, sound like a job for auto electrician.

you have to buy a towbar for your model car . as the mounting hole will be there, if you try and fit any towbar and drill holes it will affect the structure of the car the wiring for the tow bar is universal and if you get a wiring kit it will tell you how to wire it in,

Perhaps this link will be of help to you. http://www.watling-towbars.co.uk/towbars.html

You can get an adapter that fits in to the 13 pin socket that give you a 12N socket, easily available on E-bay
