So I got up under the dash and plugged in the EBC and plugged the relay in the fuse box. My question is should the "Battery Feed" wire be hot when the truck is on? I put a test light to all wire and got nothing/
I'm trying to see if I can use the power feed as a source for a few aftermarket items instead of taping into the box.
Are you talking about the Red lead in the gray 6 pin connector ?
EVTM shows it to be hot at all times.
Page 15 of the trailer tow install directions does not make a note either way :
If you look at the diagram, F105 is fed from 2 other fuses ( have not located those 2 yet ).
If I got the correct wire, it should be a 10 or 12 AWG wire, hot at all times. Keep in mind John might have actually tracked down with a meter that it is only hot in the run position, or run / assy, which would be a case of the EVTM being wrong, and one of those other 2 fuses only being hot in the run position.
I'll double check all the fueses tonight to see if something went wrong there. If I looked at it right Fuse 106 gets a hot feed and sends it to the relay that turns on when the truck is running and off when the truck is off.
I picked this up in a junkyard without noticing what year truck I found it in. Can you ID what year range it's made for? I guessed '99. I also edited the instructions down to just what's needed.

I want to say '99 was when adapters were still used to make the 4 pin trailer plug on both F-series and EXPY/Nav's. '00 was the start of the F-series having the 4 pin on the truck next to the 7 pin round connector ( if memory serves me correctly that is the -A vs. -Q on the part number).
The guts of the diagram, and the parts [i]should]/i] work on any '99 to '03 ( and '04 Heritage & Lightning ) truck, as the 2 relay locations are the same place on that series ( '97 & '98 are in a separate relay box under the hood ).
I have the directions from my '01 scanned into PDF if you want them, just drop me an email and I can send them off to you for comparison, it is a 3MB pdf file.
I plugged the harness back in, took a test light and got nothing, however the brake light leed did work. I also took the light back and tested the 7 pin and guess what has power. the battery trailer feed tab. Go figure.
Is it possible that Ford has it all prewired and connected on the 07's and that there is something else I am missing.
The Wire diagram scanned in above is the same that came with it
I have no power to the red battery feed on the harness that plugs in under the dash. but the green brake wire does light up when I press the brakes using a test light.. Truck is on when I test the pig tail
105 was blown. I took out a 30A from the passenger seat to test it and it powered up which is both good and bad.
Good that it powers up
bad that, why a truck with only 900 miles have a blown fuse already. next question is looking at the diagram it looks like it is suppose to be on key on and not battery hot and last the wife's chair wont move till i get new fues which will be priority one cause if mama aint happy ant nobody happy.
course it burned up the moonroof switch 3 days ago and it wont be at the dealer till monday....i hope this isnt the beginning of a lemon
