OK, my son's 94 f-250 has the factory plugs under it for the trailer plug.I checked them with a test light and they have all the lights and brakes wired to them.I need to put on a new 7-way and would kinda like not having to cut and splice.Anybody have a source or a part#?

 

Most trailer hitch shops will have the plug/play pigtails and plug--check with one of them.

Any RV sales stores...... or if not in hurry, 7-Way Connector Plug Female Car End - $7.99

Great price....

 

I have a new plug,I would like to keep the factory plugs off the chassis instead of cutting and splicing.It has the fact. tow package like my 95 Lightning and the brake controller was left in it by the previous owner.The factory gray plastic connectors are still under the truck at he rear.

 

Ford wiring harness has plug-in connector under the frame--just use that to hook up the new 7-pin. Or maybe I don't understand what you are trying to do.

 

I don't seem to understand either..... are you trying to EXTEND the existing 7-way?

 

The factory harness has two plugs with the trailer wires at the rear of the frame.I would like to find a pigtail to run from the plugs in the frame to the 7-way so I would'nt have to cut and splice the chassis harness .

 

Look up NumberDummy, it is going to be a Ford part that you need
