factory 7-way OBS wiring oddity
#16
yep those are it. i already have the factory rear harness. 6pin round was changed out for a 7way.
if someone needs the rear harness ill let them have it. otherwise probably good to have as a spare. but yeah if you feel like shipping that relay box it may save me a trip to the pick n pull.

I am pretty sure I have, in a pile of spare parts, the trailer relay assembly that locates outside the Power Distribution Box under the hood.
I also have the under rear bumper Ford trailer connector.
If you are interested in them , I could go take a look and verify
Let me know...
EDIT:
I think these are the OEM addtnl. trailer towing relays:
The truck I took it off of had it mounted on the rearward side of the PDB in place of the Bronco 4 relay version shown below and it plugged into the two connectors as marked:
Factory 6 round prong -under the bumper- female coupler w/ an '92 engineering id number (off of a '92 or '93 f250):
My '95 Bronco has OEM 7 blade RV Plug along with a matching Ford male plug for the trailer side in the original box
I also have the under rear bumper Ford trailer connector.

Even in the early 90's the flat bladed receptacles were mainstream on civilian type equipment

You. You dont know the difference. If you notice, in the pic That McLEOD posted(the one that you said was"exactly what I took off my 92") is indeed a 7 pin RV plug NOT a 7 pin semi plug

DieselBrad, you are confused. I KNOW what I took off my truck. You don't. If you look at the diagram on the cover of the plug posted (one I said exactly like mine) it has 7 PINS - NOT BLADES. I do know the difference, I have driven class 8 trucks for many years, and also own one, a 379 EXT. So plenty of experience with pneumatic trailers, vans, doubles, etc, ALL of which have light cords. Which incedentally, were SAME style as the FORD plug on my 92, also identical to pic. Kinda like BETA vs VHS I guess, the 7 pin never really took off in the light duty world as a standard. Seems the RV 7 blade is now the most common.

It looks just like what the chart denotes as a "7 semi".
It did come out of either a 92 or 93 F250 junkyard truck.
Up until this thread came up, I had never heard of the term "semi style"
But 94 up may be all 7 flat blade RV type though, given the responses.
My 95 Bronco has the 7 flat blade RV type (like someone would want to tow a larger trailer with a Bronco - YIKES!!)
