Currently fitting a s/h Bosal Oris-Matic retractable towbar to my Estate and I will do a how to.
I am using the VX wiring harness for 13 pin socket. This came with the instructions for the lighting connections but nothing for the switched and permanent power supplies.
Many thanks to Graeme for info on fuses however, he has a hatchback and certainly for the lighting there are some wiring differences for the lighting so do not know if that also applies to the power.
GM uses different wiring colours to the norm and in the wiring harness I have the permanent power cable if red and the ignition switched one is yellow.
If you have a factory fitted towbar I would be grateful if you would let me know where these two cables go in your car - from the length of them there must be a connector close to the trailer control module.
