The way I did mine was to remove the complete harness. As you unplug each item, tag it. Wipers, raidio, headlights, etc. The headlights, alt, etc unplug from the engine side of the firewall. There is a bolt in the center of the plug holding it in. The rear tailights unplug from under the dash to the left side of the fuse box. Easy to find, the wires run up near the emergency brake. The fuse box itself is held on by 2 screws.
The interior lighting is orange wires. All the black ground wires are soldered together halfway up the harness. Do not cut this section out, but peal the rubber off it so you can see it. Start cutting wires off the harness from the furthest unnecessary wire out and work your way back to the fuse box. Cut all the unnecessary ground wires off back as far as the soldered section and tape it back up. As you get going it will get easier and easier. When mine was finished it was 18 inches long. See pic for finished result.
