Hey Electrical People, I Gotta Question

I am in the continuing process of trying to improve the condition of my 66 4020 Gas. What I'm up to now is replacing old rotten looking wire, and getting my fender warning lights, and new back light working. I've purchased a new key switch,"due to the old one being so badly curoded", and I've purchased new fender lights and back white light. What I need to know is what gage of wire is required to make my rear wiring harness? The stuff that is on there has a real thick, but cracked and dryrotted coating, and I can't be sure when checking the wire against the size gage. So if you know what gage to use please let me know. Thank you, Greg H.

For no more than you are talking about I wouldn't go less than 18 gauge. If you can find 14 or 16 gauge use it to the back up light as it would be the one heating up the lighter wire due to being on longer at a time than the flashers. Also the heavy insulation is there for abrasion but if you wrap them with electrical or the rubber wrap tape the thickness of the insulation really want make any difference. AD

I redid the wiring to the tail lamp and generator on my 70D using SJ cord. Comes in several different gauges and numbers of conductors. (It's a tough neoprene-insulated round cable which is very abrasion resistant). Try your local hardware store or electrical supply house. Looks neat too, although it won't satisfy the "correct police". In my experience vinyl electrical tape eventually comes unstuck or cracks, and flaps loose around the wires at the worst times, especially important "hot" connections passing close to grounded metal. I use soldered connections and shrink tubing; I've never had a properly soldered and protected joint corrode or fail...

I've had excellent results with rewiring old tractors, etc with SJO cord - similar to SO but with improved oil resistance. Available in sizes from up to AWG #16 to #10 and with 2 to 6 conductors. Like you noted, it doesn't meet the standards of the "correct police", but it will easily outlast OEM-spec wiring, especially if terminals are crimped/soldered and shrinkwrap is applied. The stuff is also easy to work with, and makes a neat-looking job when finished.

Use 14 ga. wire on everything except gen. or alt. then use 10 ga. wire. Check at your local Napa parts house for asphalt loom it comes in several sizes and will last for years and makes a clean install, use shrink tubing on all wire ends.
