that doesn't sound right . the one i bought was the same as the original.Russ, my new harness came with a template to increase the size of the hole in the firewall. I understand your harness is from Year One, I believe it is actually made by American Autowire, like mine
Ya I heard M&H has good tech support. I'm probably a year from installing any wiring. I just welded in a new Dutchman Panel and repaired the rear window frame.No cutting with the one from Year one. Will say if you buy the hole harness under dash some color's did change on mine and had to call the guys that made the harness.
