Need some wiring advice
Morning.
I have a 1994 F350 that I purchased about a month ago. I want to rig it up to pull a trailer or a 5th wheel equipped with brakes, so I need to install a 7 pin connector. It has a 4 pin wire harness on it, plugged into the harness by the spare tire. Under the dash I found the connector for the brake controller, so I bought the connecting harness (from this site!) and am just waiting to receive it. I have a brake controller ready to install.
Under the hood in the fuse box I see 2 fuses, one for the brakes and the other is probably for the 12V+ for trailer battery charging.
Now I have to find the brake and 12V wiring at the back of the truck. Would it be tucked inside the harness where the 4 pin adaptor plugs in? Or did Ford terminate it some where else as I have read in some other posts?
Thanks in advance for any help, this is an awesome site!

the wires all terminate at the back of the truck, with a pigtail that the wires are just cut off, left side rear corner. Thing is, they may not have connecterd at the front of the truck if it is not a camper special. The wires are all there, you just have to find how to hook them up. I ran into this with my 92...
