Fitting towbar electrics
Hi, I'm Peter, You do not need to access a panel to wire up the electrics for the tow bar on a 2003 Kia Sorento . I don't know if you have the tow bar yet or not but there is a bolt in model for the Sorento 4 bolts and your done it's on there too. The wiring is as simple also. Kia actually has a wiring harness that all you do is plug it into the existing plug and you have a ground wire to attach which they also have already on the car. I just got through swapping the same setup from one 2003 to another in about 20-30 minutes, I had an impact gun though for the tow bar bolts. The wiring you are looking for is located between the frame and the body of the car on the passenger side. As you lay on your back you will see it is connected to the frame with a push in connector or tie wrap I can't remember right at this moment it's 1:30 AM. Just get it loose from the frame and disconnect the plug that will continue on up towards the right rear tail light.. Take your harness ( believe me it's worth getting from the dealership) and plug it in between the other two connectors. Like I said earlier you will have a black ground wire and if you look on the car body portion you will see a bolt hole located a little past half way of the flat vertical area , that is where the ground wire goes. There may be after market harnesses just like the one the dealership has but I already had one so I know everything fits perfect and the trailer plug end will go across to the driver side of the center of the hitch where they normally are. I have to tell you it was one of the easiest setups I have ever done and I have head remarkable stories about how strong those hitches are when other vehicles run into them. The other vehicle is destroyed and the tow bar protected the KIA. If your going to do it do it right and easy. Good Luck.
