I've checked into this wire it's brown with a white tracer and isn't shown on any diagrams I've seen on here. Ive been redoing my harnesses and traced every wire on the truck.. that wire is connected to the back side fused blade of the radio fuse holder and is key power only. It does not come up behind the dash for anything, it just goes through the firewall connector and into the harness in the gutter above the engine. My guess would be a power antenna where it runs off the radio fuse. I left it there for exactly that reason.. figured I'd find one and install it someday.
