[AT] @!#%^% Trailer Wiring

[Len Rugen]

On my recient trip, I needed to add a 6 pin trailer connector to my truck.
My son got a plug that had both the 4 pin and 6 pin.  Handy, it just plugged
into my factory 4-pin plug.  I connected the trailer brake per the diagram.
OK, but it didn't match the trailer.  So we swapped the trailer and drove.

Now we're back and I need to put things "right".  It appears that there is
not a standard for 6-pin plugs.  My diagram said brake was to the center
pin, aux power at about 2 o'clock.  Local trailer shop diagrams have these
reversed.  Sigh...

Also, factory wiring loom on my '95 F150 isn't labeled for an AUX power /
trailer battery charge circuit.  It has a BLUE wire for brake, as it should,
but an ORANGE and BLACK that are apparently neither grounded or hot at any
time.  Another sigh...

I don't know if I have a question or not, unless someone has ever fought a
F150 of that era.  I'm just typing this instead of cussing.....
