Electrical help needed, underdash wiring is a disaster

I disagree that complete dash assembly is easy to remove for the simple reason to remove it, the dang windshield needs to be removed. That’s a non-starter for a lot of people! I agree that when it’s on the bench, then it’s a piece of cake to get at everything.

We didn't remove the dash but the gauge cluster and then the entire harness. Really not difficult at all but we did remove the front bench seat and laid out some moving blanket for comfort.
