I would like to beat the inventor of Scotch - Locks into a bloody pulp. The ONLY thing they are good for is to let people who have no business working on vehicle wiring, completely, and utterly, screw up a good wiring harness.
Whomever wired my Grand Cherokee for trailer connectors must have used a whole box of the things. And all they managed to do was let water wick up into the wires, and corrode them all to hell. Which in turn, blew out the Lamp Outage Module, and constantly made the Jeep beep, and tell me my rear lights were out. After working on it all day yesterday, I have all the lights working on the rear, fixed the Lamp Outage Module, have working flat 4 pin, and round 7 pin trailer plugs with trailer brakes, and made my own separate brake / turn flasher module with relays. Everything is soldered, and sealed with adhesive lined heat shrink tubing, and tied up out of the way. Why can't people just do it right the first time?
Do little things like that just bug the heck out of anyone else? Or, am I just a whiney little *****
