1969 Camaro Restomod
Its a true mystery wire. You can check out the thread The Mystery Wire. And I did correspond with Larry Dubois who is the guy that pieced together all the electrical schematics for the '69 Camaro. Larry sells the PDF "book" on eBay or he did at one time. I actually bought it, printed it, and made a spiral bound real flip page reference book I keep in my garage. Larry was baffled but thought the wire might have something to do with the ignition because it looks pink even though its very heavy gauge. I have too many wires hanging in the engine bay to put the battery in just now, plus I'm a little less mobile with this soft cast.
