Well, I did it, I finally caved and drove the truck into the shop. I can say the mechanic has earned his money... I've given it my best (which when it comes to electronic components in vehicles, I am out of my elements).
The drive to the dealership was interesting... I utilized my newly found trick... under the steering column is a little sliding door. It exposes a slot big enough to fit a key in to push a lever inside the column overriding the security lock on the shifter lever. Now I have the replacement 4x4 CM in place, replaced blown fuse (#27) and have in hand the brake switch. I chose not to touch the brake switch due to a recall needing rewiring and I have remote starter installed which is on the line with the brake switch. So the 4x4 lights are not working at all now... off to the shop I drive... yeah, it was a fun 6 1/2 mile drive going around 25-30 miles per hour... Which here is an interesting bonus!! My speedometer is saying I am driving around 80-90 MPH!! It feels like I am in 4x4Low... FUN FUN FUN
