Where are the connection points of the infamous RED WIRE?

[Wishbone]

I understand the infamous RED WIRE from the fuse block near the battery feeds the constant 12V (Auxillary) to the trailer power plug. I've had it connected for years, but I checked it this year and there's no 12V at the plug. Can anyone tell me the specific locations of the the connection points for this wire between the fuse block by the battery to the plug at the rear of the vehicle? I want to track it down to find the break but don't necessarily want to follow each wiring bundle by hand under the vehicle. Any help would be appreciated.

Verifying that the stud is getting power at the fuse block would be a good place to start. It is a fused circuit, if the fuse is blown you might have a short somewhere down the line. Also make sure there is a fuse installed for it, maybe the fuse is missing (30A j-case)

Next thing to check if you have power at the stud and the wire is connected would be to check for power at the backend of the trailer plug where the wire goes in.

If there's power at the stud and at the end of the wire at the plug, the plug is bad. If power at the stud and no power at end of the wire then there's a break somewhere in the wire.

Yes, of course. I've verified power at the the stud on the fuse block/wire connected. I've verified no power at the plug or wire leading to the plug at the rear of the vehicle. It's the connection points in between I'm looking for. I know it's not one continuous piece of wire, there are connection blocks in the wiring harnesses. THAT'S what I'm asking for... Locations of the break points.

service manual shows a single length of wire, no connectors. runs along the left frame rail.

Thanks @coolasice , I thought for sure it was not one piece of wire! Wadda ya know. I'll trace it down tomorrow then.
