How to insulate wires from each other?

The method I took to insulate the wires from each other was to insulate each of the wires after solder them. That is to say, after soldering the white to white wire, I then insulated it. The rationale for that is that it is easier to do this while they are separated than to try and do this after they are all soldered.#N#Once they are all soldered and insulated individually, group them together and insulate them together using liquid tape. You can bypass liquid tape for this last step if you are able to get your hands on shrink tubing small enough for this size wire harness AND remember to position it prior to starting the soldering of the wires.

How to solder wires?

In order to solder the wires, secure one half of the wire harness in a panavise or one of the clips from the third hand, and the second half of the wire harness to another of the clips from the third hand.

Instead, unbraid the wires from the one half, and unbraid the wires from the other half of the wire as well. Then bring them both together and squeeze them so they mesh together. Now solder. Follow these steps for all of the wires. Remember to solder white to white, black to black, green to green, and red to red.
