Acces key on wire
I just put in a 6 point hitch plug and was wondering where would be the best place to wire a hot wire that is on with the key in the on position, so my battery does not drain if I leave a trailer plugged up. Thanks.

Ford puts that relay in the engine compartment on the driver's front wheelwell and it's triggered by the same circuit that energizes the oxygen sensor heater (Ppl/Or). You should be able to find that relay assembly at a junkyard and plug it into your truck's harness.

I don't want a heavy load going to the trailer maybe 20 amps at best. And my truck does have a relay that says trailer harness, so where could I trace this to find it in the rear of the truck.

Follow the harness coming off that relay block - if there's an unused connector on it, you may not actually have the wiring at the back of the truck. Get a Haynes manual and compare the wiring diagrams to what you find on your truck. That harness should run down the L frame rail all the way to the bumper.

Franklin2, Excellent drawing! I do this kind of drawing on my Autosketch program but have not figured out how to post it here.

Go to your gallery and create a new album in addition to the album you already have. Call it mantta's diagrams or something. When you are naming the new album, make sure you check the box on the bottom that says "hide the album". They don't want diagrams with people's trucks in the gallery.
Once you have the album made, you can upload a diagram you have made from your computer. I don't know how big it can be now, but it used to be limited to 700x700 pixels. I do mine in paint. I just go to attributes and make the drawing size 700x700. Whatever program you use, make sure you do a "save as" and change it to a .jpg or .gif. Mine are done in .bmp so I save as .jpg. After you upload, look down at the thumbnails at the bottom of the page and click on "forum codes" Copy the link and then go back to your reply and paste it in. The [ img ] and [ /img ] at the begining and the end make it magically appear.
