Harnessed with problems
I got distracted the last time we took our fifth wheel out, and I ended up breaking the plug for the wiring harness in my truck.
Yesterday I finally got around to replacing it. However, I didn't notice until I got the last wire undone from the old 7-pin plug that the wires weren't the same color as what was written on the plug.
I've spent the last two days trying to figure out which wire goes where.
The 7-pin has spots for Black Blue Red Brown Green and White.
The wires coming out from under the truck are Black, Blue, Red, Brown, Green, and YELLOW.
I tracked the wires down to the bumper plug on my 2004 F250, and then back up to where it plugs into the harness.
I still can't make much sense of what I've got, since the colors under the truck don't make much sense, either.
Blue connects to Blue, and
Green connects to Green
Black connects to White
Brown connects to Black.
Red connects to ... Orange?
Yellow connects to ... Yellow?
If I connect everything sorta like the above (there is no orange or yellow on the 7-pin), I can get the brake controller to show that it is connected, and it will give me a reading if I push on the brake.
However, the brake controller will do the same if I connect Blue to blue and Black to black. Or Blue to white and Black to Blue.
Yesterday, I while poking around on the various options, I did manage to let loose a few sparks. I've checked all of my breakers and fuses INSIDE the trailer.
Since nothing lights up, no matter how I connect things (other than the brake controller) I'm wondering if there might be another fuse in the RV that I'm missing.
Failing that, does anyone out there know how the 7-pin should be connected to an F250 when the standard color code doesn't work?
Thanks for any help you can through my way!
