The ciggie plug melted long ago and I wired up one of those 3/16" cannon

off-the-shelf solution which doesn't take up much room? The whole ciggie
plug thing is the dumbest convention ever, I must say. I can't believe
it's still extant.

Look into Anderson PowerPole connectors.

You can find them -- and the crimpers needed for them -- on the
QuickSilver web page which mostly sells to ham radio operators.

http://qsradio.com/Powerpoles.htm

You can get terminals for these for 15, 30, and 45 Amps.

The shells come as individual wire shells, or as solvent-welded pairs
(Red & Black). The individual ones come with dovetails so they can be
slid together to make pairs, or larger counts of pins at need. Lots of
other individual colors available. And mounting blocks to make them
panel mount. (They are normally just wire mounted on both ends. :-)

They are both insulated at both ends and keyed so they will only
go together the right way.



Plan on having a really good grip to operate the crimper,
depending on which terminal you use. The barrel style crimps seem to
take more force than the folded flag style (which is the 45 Amp
terminal).

The WPL-7PK45 set has seven pairs of terminals with the 45-amp
crimp terminals and the solvent-welded Red/Black shells. ($13.00 for
the set).

My buddy Glenn showed me that you could remove the soldering tip from
a Weller 150W gun and induction-heat the terminal to solder the wire
in. It worked extremely well for the 4ga armored wire he gave me to
use with the towing-receiver-mounted winch. http://tinyurl.com/nejufw9

I used the Anderson Powerpoles on the winch wiring, and I'm not all
that impressed. They're less reliable than I had hoped, and I've had
to reseat the things several times in the past, though they seem to
plug right together. It's usually not more than one extra 'fiddle'
per use, but that's once too many. I prefer plug-n-play hardware,
TYVM.
