WA Wiring harness, under dash with gauges type, very clean.

Had a scotch lock wire tap on the brake wire for brake controller, I installed heat shrink to repair it.
These are very hard to find this clean.
$140 shipped.

It’s a long answer....
AC is a separate harness that connects to the standard under dash harness. The connection is to the larger brown wire in center left of picture 1, where it’s in a connector with orange and yellow wires.
67-8 under dash wiring harnesses are different in basically one way, the fuse box mounts higher up the firewall and is horizontal vs vertical. THe 67+8 fuse box is different shape too.
This one is not a direct bolt in.

Inside harnesses are for with or without gauges and for 4 speed or auto/3 speed manual trans.
This is for gauges with auto/3 speed manual trans and fits 69-72

I used a ‘69 harness in my ‘67 GMC and it bolted in with no issues. I did have to lengthen the wires for the wiper switch though

Did you screw it in sideways like 68 is mounted? Where the screw holes the same?

Screw holes are the same. I did separate the half’s and move the NSS/BU wiring to be on the bottom like the OG is though.
