The wires were cut behind the towing plug and plug was taken. i need to know which wires are what cause the replacement plug from ford is not color coded

quickest fix
go to the wreckers/ junk yard and cut off the data connection plug leaving around 6 " of wire
cut of your data connection plug and then reconnect the replacement plug wie color to wire color
solder connections and seal off with shrink tube wrap

the secret here is to buy a trailer harness for the vehicle ( available from most tow bar supply and fitting shops )
it is a set that just plugs into the existing harness at the rear light assembly ( piggy back arrangement)
from there you wire the male and female plugs as per the color code that is on the paper that comes with the units
saves cutting into the car harness and causing real electrical problems

take a close look at where he cut the wires. you may see a little of the wire colours in the plug. why would he cut the connector off. with most people having a phone capable of taking photos I`m surprised no photo taken before this happening.

here is what for manual gave me

Click on the link, hope it helps.

if you go to the parts store they make them ready to plug in you will have to just unplug the tail lights and plug the wire harness inplace of it then itll plug back into the original spot.

use the tow connector located behind the tire jack mount at the rear :)

I take it the blinkers and brake lights work ok when not hooked up to the trailer? If yes, then the wiring to the tow hitch is not hooked up correctly. How many wires to trailer pig tail connection? U can have up to 7 depending on what you tow. Check to make sure these wires are hooked up from the truck to tow plug correctly: 7 wired---
brown-Rt turn and brake light, yellow-backup, white-ground, blue-electric brake, green-tail running lights, black-battery charger, red-left turn signal and brake light. Let me know if u have something other than 7 wire, I'll get the wiring color and source info for u.

Here are the factory wire colors, please rate this solution to your problem, a note any stereo store that sells auto decks has adapter wiring harnesses to do a direct plug in of your DIN standard radio you are trying to install, no cutting of the factory harness, they are cheap
