[SEL] O.T. O.T. Dodge Wiring Problem UPDATE!

[Doug Tallman]

Paul, did you change the pigtail end on the harness to the switch?? That 
is a must when there are signs of overheating in that area. The 
teerminals loose their tension and just burns up the new switch from 
poor contact. you need to solder the wires when you connect them. Also, 
when the trailer hitch was removed, was it a simple unplug or has the 
harness been butchered back there? Doug Tallman
