You can search the subject on the forum for some more info but buy the dedicated wiring harness, it is so easy to fit, the harness is only short and just plugs in under the car to a pre wired plug, no ecu mapping is needed just plug and play, you can see the plug it connects too, if you need fridge power and battery charging this is a 2 cable seperste harness but again it runs from the battery of the car (small relay and2 fuses under the bonnet) back to the same location as the mentioned plug under the car so no trim removal at all. The dedicated loom also gives you the benefit of the dash board towing warning light and I believe this is the trigger for the operation of the trailer stability control that's built into the Antara, a good safety feature you want.
