[QUOTE="jeepjoe43, post: 428660, member: 19255"] It's Major Pain in the Butt to remove and rebuild a harness, but at least you will KNOW what you have. With a used harness you're probably buying problems from someone else. This is my 10 step program to go about rebuilding one. 1 Label All of the connectors and carefully remove the harness from the vehicle. 2 Spread the harness out on piece of plywood securing all the connector with screws and zip ties. 3 Use screws or nails to mark everywhere the harness branches so you get them back in the right place later. 4 Inspect all the connectors for corrosion or other damage. (Probably where you'll find your issue if it's the harness) 5 Remove all of split loom and label the size of the loom on the plywood. 6 Inspect for physical damage to the wires. Wiring faults tend to be obvious, but are usually at a connector or a splice. 7 Use a meter to check the continuity of each circuit, wiggling each connection as you go. 8 Repair or replace any faults found, most of the connectors can be disassembled with the right tools if needed. You won't be able to "uncrimp" an original connector, but you can solder a new wire to it. 9 Replace the split loom with New and Gaffers tape or branch connectors where needed. 10 Reinstall. You will likely have found and fixed the problem, and it'll be pretty again. As a laddy my father taught me that if you're going to take something apart to fix it, clean it, fix it, paint it if needed and make it New. Doesn't work in every situation, but that's my Modus Operondi. [/QUOTE]
