Under dash wiring harness routing

73429mach · Sep 2, 2018

I will be installing my under dash wiring harness and dash soon. When I removed it I didn’t take a lot of pictures of how it was routed. Does anyone have any pics with the dash out showing the routing of the harness? Thanks, Ryan

The harness will normally lay in place once you start popping clips in. I don't have any under dash pics, but here's the page from the MPC.

Here are some more. This is a 73 vert with gauges, convenience group, AM/FM, air so each one is slightly different in amount of plugs and wires. I also ordered some of the foam foil backed sticky sound / heat insulation and applied to the bottom of the cowl. The old factory that had the plastic and 1/2" thick insulation had fallen apart.

Where did you get the insulation?
