61polara 270 Posted January 20 I'm trying to build some documentation on this. What years did the auto manufacturers switch from cloth covered insulation to plastic on their wiring. Also, what years did they switch from cloth wrap to a plastic wrap? Photos of original cars will be a plus. Share this post Link to post Share on other sites
Bimus 3 Posted January 20 I have noticed 53 Chevrolet cars with cloth or plastic covered wires and though maybe early 53's had cloth and later 53's had plastic covered . Share this post Link to post Share on other sites
misterc9 49 Posted January 21 A lot of cars switched to plastic insulation when the went to the twelve volt system. 1956 for a lot of cars, earlier for GM. Share this post Link to post Share on other sites
