i need to tow a trailer tomorrow which has a 7 pin plug on it. i dragged a$$ on my plug shortly after i got the truck and messed up the plug. so i went to walmart, bought a new 7 pin plug for $20 and i just need to wire in all the old wires into the new one.

i need to know what colors are for what function. IE...white=ground etc. please help, i need it fast.

 

truck--------------- controller---------------- what it does

New Ford (Pink Wire) -------------- Pink Black --------- +12 Volts
Red --------------- Red ---------- Stoplight
White -------------- White ------------ Ground
Blue --------------- Blue ---------- Trailer Brakes
Brown --------------- N/A

Ford - older
Red --------------- Black ---------- +12 Volts
Lt Green -------------- Red ----------- Stoplight
White ---------------- White --------- Ground
Dark Blue ---------------- Blue --------- Trailer Brakes
Brown ----------------- N/A

 

wait what? you only listed 5 wires. i have 7. and how is brown not used? it has to go to one of the pins...

 

ok, if you promise to be a good boy.
Off a Ford service disc as C456 info page.
1 = YEL = L turn.
2 = WHT = gnd.
3 = Dk Blu = elect. brakes.
4.= Dk Gn = Right turn.
5 = Orange = battery.
6 = Brn / Wht = running lamps.
7 = Blk / Lt Gn = reverse lamps.
The terminal count begins at 11 o'clock from the socket key and goes counter clockwise to term 6 at 1 o'clock looking at the front of the socket
Term 7 is inside the center..
.
It is remotely possible the color code might be different.
Use of a voltmeter will ID all the functions.
For example; put the 4 ways on and see terms 1 and 4 flash power and left/right single turn signals.
Good luck.

 

dude, your a beast. thank you soooo much. between me and my dad googling, we couldnt find a straight answer. thanks again.

only difference is i dont have an orange, i have a red. but its a thicker wire so im guessing that is the battery.

 

Try this Diagram also, same as above, but it has pics!

thanks guys. between you guys and some other people, i got it all done. now out to hook it up. hopefully it all works. heres some pics, and a pic of why i needed to replace the old one.

 

good! that means i did it right!

 

I wired my trailer and left side works but not the right side. I check the connection at the truck and the yellow wire is hot but not the green one, I think the problem is at the truck connection.
