The real trick in routing it lies in having it long enough to reach when turned fully both ways, but too short to get near the ground.
Bingo,
My Dodge 2500 has the connector to the left and to far away from the hitch, it should be as close as possible to the receiver. This requires more cable when I make a right hand turn. If cable is not long enough it can pull right out when making the turn.
If you have 7 pin connector it should spring load shut on the vehicle and lock the connection in place. If you do not push it in all the way the lock on the cover will not hook up with the connector.
As far as repair I found the best way to repair is with solder and heat shrink. With this method water will not be an issue and you can splice in where ever you want as long as its easy to get to with a solder iron.
