Somehow my headlight wires broke in half, they broke off right at the connector, so I had to do a little more than just splice the wires together, I had to recycle the pin connectors. There was also some rub wear on other wires behind the number plate. Use a small flatblade to remove the pin from the connector housing, be careful, these are not the type of thing you can buy at radio shack. Use the flatblade to carefully bend the tabs holding the plug to the pin. Leave about 3/8ths of an inch of wire attached to the pin and strip the insulation off, slide plug onto the new wire and attach the new wire to the pin. Solder the new wire to the pin. Slide the plug up to the pin, and reform tabs to hold plug, finesse is key here, dont trash anything. Ok, here is the first layer of shrink wrap, it is the standard Polyolefin type, it stays flexible after shrinking, I will apply a second layer of PVC Shrink wrap to provide some durability and to prevent the new wires from twisting off at the connector. One wire down one to go. Ready to splice onto the main harness. A couple other wires had insulation that had been compromised, I shrink wrapped them with the red shrinkwrap, you need to pull the wires from the connector housing, slide the rubber plug down the wire, then apply shrinkwrap. Shrinkwrap is much cleaner and more functional than black tape. Splice the repaired connector and wires to the main harness, use solder to join the wires, shrinkwrap the individual wires then wrap the entire thing.
