I have a 2012 Hyundai ix35& have fitted a towbar wiring loom.

the reversing sensors have to be recalibrated for the towed vehicle
all is explained in the owners hand book for the vehicle

There is a short circuit in the Radio's power line... there is a cluster that is probably fully or partialy melted...

if you have the proper kit , the it is a simple matter of pulling the harness connector from a tail light assemble and inserting the harness on to the assembly the fitting the harness back on to it
the wires are color coded and all new trailer plug connections have the pin numbers for the color wire to get the correct lights working at the back
if you are not power or circuit savvy then get the towbar shop to wire it up or get an auto electrician to do the job

there should not be if you use the extra wiring harness that will be available with the tow bar and follow the standard wiring diagram that comes with the plug for the trailer lights

unfortunately with the regulations as they are you will have to have the tow bar fitted at an accredited towbar shop as you will need a modification plate fixed to the vehicle fire wall by the registered installer. If you have a machinery inspection and there is no mod plate then you will be put off the road

Hi There. Im not sure where you are but this is the sequence for the UK< Hope it helps.
here are the 7 cable locations and pin numbers.
Pin 1 Yellow L/H Direction Indicator
Pin 2 Blue Rear Fog Lamps
Pin 3 White Earth Return
Pin 4 Green R/H Direction Indicator
Pin 5 Brown R/H Tail & No, Plate Light
Pin 6 Red Stop Lamps
Pin 7 Black L/H Tail & No, Plate Lights

I found the easiest way to locate the correct wires in the loom is to turn on the lights required and use a circuit tester and splice into the main loom where you have enough wire to play with. Try not to cut the loom as it only causes more problems with bad connections and joins.(
Good Luck

The best, and in fact the only recommended solution is to use a plug-in dedicated wiring kit for this car, it plugs into a grey connector on the chassis on the rear of the left hand side. this is the connector that the cars rear light loom is plugged into and the towbar loom piggybacks onto this using the same watertight sealed connectors. There is a trailer indicator warning light already built into the dash display so no need for any other monitoring of the trailer functions. This wiring kit should cost you around £40-£50 and will only take around 10mins to fit. The other alternative is to solder the towbar wires to the cars loom, but this is time consuming and may invalidate the vehicles warranty.

I assume that the towbar didn't come with a proper wiring kit as, unfortunately there is not a specific connector for the towbar wiring on the x-type, the proper Vehicle Specific Kit plugs into the rear light. There is a power connector with three pins on the left and a grey reverse sensor cut out connector also on the left. but you will either need to use a Vehicle Specific Wiring kit (about £175) or use a bypass relay system.

The connectors for towing wire harnesses on foresters are generally on the passenger side, below the rear taillight inside the cargo space. some require pulling up the foam block that is between the spare tire compartment and the taillight. Check where you replace the tailights from inside the car, if there isn't a matching connector hanging out there, check around the spare tire compartment, see if you can remove the carpeted foam block next to the compartment and find the plug under there.
