I really like this Curt wire harness. It is so easy to install into the existing wiring. No splicing required. Just pull out the wire fitting from the 7 way trailer plug and then plug in the new one. Drill hole in truck bed side wall. Feed wire end through hole and plug new 7 way into the end. Mount to side wall with 4 screws. All done.
