VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1937-1945 1938 Individual Wire Colors?

OK, I'm exhausted using the "search" function looking for my answer.
1. What is the entire color codes for 1938 master/master deluxe?
2. Is there a site or has anyone put together an entire chart identifying all of the different wire color applications?
- I want to rewire my GM defrost fan and fog lights but want to use as close to correct colors as possible. I did see some references here and there, but nothing in its entirety.
- I did visit Rhode Island Wiring's site and am very impressed, too many options.
-I build commercial aircraft wiring harnesses for 18 years so building and terminating is easy, but identifying what is period correct or close is the challenge. I will run wires individually as i go along verses buying a harness
Thanks

The factory wiring shows only the wires that were used on the car in production. This means that any accessories will not be included. This would include heater, radio, and any lights, etc.
From my experiance I have found the the accessories (they came with the neecessary wires) came with black (very dark gray) cloth covered wires. 16 gauge was used 99% of the time. They correct way to wire was in the instruction sheet that came with the accessory.

My 1939 shop manual shows the wires but no color coding is shown. My 1942 shop manual shows the wire gauge and wire color code. In general the wire code stays the same for a given part.

My son also builds air craft wire harnesses.

I just remembered that my 1939 (no long own) had silver cloth covers wires for the Guide fog lamps, at least in the area that was exposed at the lamp.

Thanks, nothing looks sweeter than clean colored cloth covered wire in vintage cars. Haven’t built harnesses for a while but your son will attest conductor identification, ideally each system would have its unique color, ignition, lighting exterior, lighting interior, fuel, etc... for the sake of troubleshooting. Commercial passenger aircraft have lots of wires so you want to know what system and particular conductor you need to change or add in some cases. So many options for colors, I often notice folks use yellow cloth covered wire for exposed light wire
Thanks much

The original wiring was generally tan with with a coded tracer color thread for identification. The tracer thread was like blue, green, etc. Yellow covered wire would look too fake as tan was used.

Don't forget, the outer cloth covering had what looked like hooks in it that were attached in specific locations to anchor the harness to the car.
