If you're dealing with broken connectors, brittle wires, corrosion, or intermittent electrical issues, replacing the connector with a pigtail is often the best fix. Kyle walks you through cutting back damaged wiring, matching wire colors, making solid connections, and sealing everything so. Follow these steps to create safe and reliable connections. First, measure the wires you need. No confusion, no part hunting, just results. Pigtails are. Second, how do you remove the old connector and install the new one? Also, I haven't been able to figure out of what each pin does from what I've searched on other threads.
