[DeTomaso] Tach wiring help needed

[JDeRyke at aol.com]

Larry, on the back of a factory schematic dates 6/15/72 in my library is an 
illiustration of the backside of a Pantera dash WITH all the wires 
connected. It shows a light blue/black wire by itself on the tach. Matter of fact, 
on the entire dash assembly, there is no plain blue wire except to the 
emergency flasher some distance away. Perhaps someone added it for some unknown 
reason? Or the infamous DeTomaso random-color match for wiring is in play 
here?
Good luck- J Deryke (who hates wiring problems!)
