[VAC] Re: Pigtail wiring problem on 68 Overlander

John,
 I don't think I replied to this, just found it in my INBOX folder.
(oldtimers' disease, I guess)

That small metal box thingy is a circuit breaker and is probably in
either the BATT line going to the trailer for charging from the tow
vehicle or it could be in the hot lead that goes to the breakaway switch
on the tongue of the trailer.

If you've wired the pigtail with the standard wire color code, the best
thing is to disconnect all the wires under the bellypan and reconnect
them in proper sequence. The cable from the truck should have
White=Ground, Black=Hot. The trailer should have a White=Ground (go
ahead and connect them) and probably a heavy-guage Blue, or maybe Black
which will be the hot wire to the battery. Connect this to the pigtail's
Black.

Using that Hot wire from the truck, connect it momentarily to each of
the other wires to find out what they do. Temporarily put an inline fuse
in the circuit to prevent burning anything up. If the Black wire from
the truck isn't 'hot', fix that at the truck.

I think the green wire in the trailer is tail/clearance lights, the
yellow in the pigtail will probably be left over unless you have backup
lights on the trailer. If you do, and want them working, you can connect
the yellow wire accordingly, but you'll probably have to also find the
B/U light circuit in the truck and connect it on that end also.

Hope it helps, and isn't too late!!
