you can get the 4 pin 7 pin plug combo from ford the single 4 pin unplugs from a harness located under the truck if i recall in two places and is grounded above the spare tire

the plugs should be located on the left side of the frame rail located near the spare tire
if you pick one up from Ford there will be directions with on how to install it

hope this helps u out some

i would go out and takes pics but my truck is a the dealership right now

u need this part number if you dont have reverse sensors: 8L3Z-15A416-A
change the "A" to a "B" if you have the reverse sensors.

then you will need this for the bracket to hold the connector since ford doesnt make one: http://store.uhaul.com/Wiring__light...lat_Connectors

it will give you an extra connector, but u will need the bracket unless you can make one yourself.

hope this helps!!!
