Wiring Schematic

Anyone have a copy of the wiring diagrams for a 94 W9? I have a wiring issue that I can't find.

When I activate the brake lights my fender markers/signals light up as well as the green turn signal indicators on the dash. It's very faint and only visible at night unless I plug a trailer in then you can see it in the day time.

 

It definitely seems like the brake circuit is backfeeding into a place it shouldn't be. Maybe I'll try wiring a complete new ground to the tail lights and see if that helps.

 

That was the first thing I did. Haven't moved into the next run other than what I can easily see before it tucks into the frame channel.

 

I replaced the entire cord a week ago. I've inspected the line going to it thoroughly and didn't see any places for corrosion. It's wrapped pretty good and dry but plan to replace it soon anyway.

 

Thanks! I bet that drove you crazy. I'm still working on it. I'm thinking it's in the marker light circuit that's rubbing into the brake light circuit somewhere. When it's dark you can see the turn signal/marker lights barely glow when I hit the brakes.

Once a trailer is hooked up it's intensified. The symptoms are a little different depending on which trailer I'm hooked to but there's no doubt the issue is on the truck side. At least I got that far with figuring it out I guess
