I've got the 1-2 and 3-4 switches pegged, but they have red/blue and red/black coming off of them. I'm beginning to think that the guys routed the harnesses under there a little wrong, since distances and locations aren't matching up very well.

What is the switch high on the driver's side on the gear control box with doubled blue/yellow wires on it? I found the harness that has matching wires, and connected them, but there seems to be a lot of slack here in this loop. That's one of the things that is making me think that the harnesses didn't get routed where they were intended.
