My SX with the tow package has a built-in 4-pin connector whereas my boat trailer with surge brakes has a flat 5-pin plug. The fifth pin deactivates the surge brakes when backing up. Does Kia have a harness to convert to a 5-pin flat plug? Or has anyone found a conversion kit?

Any tow shop can rewire that harness., though if I were you I would switch to a round 6 pin setup in case you get a bigger boat trailer or travel trailer with brakes. I installed a round six pin for our towing needs and have a 4 pin adapter for the smaller utility trailer.

I haven't seen a 5 pin in ages.
