Full Re-Wiring Job - Help, Ideas & Sources needed.

I differ from Crackedback but to each their own. Much has to do with doing things proper whether it be proper soldering techniques or using the right connectors and crimping tools. I have wired many a harley and custom bike and butt connectors are not a real good solution in high vibration environments and are more prone to corrosion intrusion. I either use tinned connectors, crimp and solder or, pull sheaths and tin the connectors myself. But connectors tend to add more resistance to a line then soldering which is not a big issue with our cars, but can be if you're dealing with an ECM or body control module on later model stuff where stuff works off a very narrow voltage range. I'm probably over anal but I also like to loom up, route, and support the wiring so that I don't have it holding itself up by the connections or terminal ends. Whether soldered or connectors they need support or they can fray at the end of the joint. Oftentimes when unwrapping a factory harness you'll find a plastic gizmo or a length of wire that is looped or folded and taped back in at y joints etc. It's there to support the joint.

Heat shrink, terminal ends, wire tires, junction blocks or plug ends etc. can add a good chunk of change to the project.
