[A/S] Wiring????

[Dan Gerous <dngreenlee@xxxxxxxxx>]

    I backed my "new to me" truck up to my trailer to
move it out of Rita's way only to discover the truck
receptacle was wired with a round pin connector
instead of a flat.  Eh, no problem, after all I am an
electrician.
   So off I trundle to the parts store and get the
proper receptacle. Bring it home, pull the offending
one, and discover the PO has wired it all with the
same color wire. Eh, no problem, (see above). So I
sort it all out, tag the leads, and pull out my trusty
A/S owners manual to see how it should be pinned. Not
being sure which side of the trailer plug is
illustrated, I  check out the trailer pinning so as to
get the proper orientation. Now it starts to get fun,
as neither one of my units (66's) are pinned according
to the diagram.
   The new receptacle came with pin numbring and a
wiring function assignment that in no way was the same
as the assignments in the manual. So I went here...

and the pinning is way different. If this is now a
standard then I'm off to repin my plugs.
    I still need to dig into the brakes.  The
controller installed in my truck has a four pointed
star with the initials K and H, (Kelsey-Hayes?) works
off of brake line pressure and will present 12 volts
to the electric brake wire when the brakes are
applied, but the brakes won't activate. I have  a
Kelsey-Hayes manual which also came with the trailer.
It  shows a different control unit but the wiring
assignments seem to be the same.
    If I apply 12 volts from a battery directly to the
trailer brake line should I be able to hear the
magnets clamping to the armature plates? Does anyone
know what the continuity measurment of a magnet should
be?
  Thanks,
