12 volt power socket installed in 177

No, if assembled correctly they will always maintain polarity correctness.   Each connector is marked as to which contact is positive on the two conductor ones.  I've never had a need to use the individual contact version since I've only used them on 12V DC systems where both + and - are needed.

Roll pins?   Lost me there.....haven't seen that on the ones I've used.

Originally posted by CharlieM Bud, I've seen the Andersons advertised, but never seen one in person. How do they handle keying or polarity? Will two reds mate, two blacks mate, but not a red and a black? Or is it something else. Also have you ever seen a panel mount version? Any connector system to replace the cig plug will have to have a panel mount female and cable mount male.

The colors are simply to identify different "systems".  The colors have nothing to do with which ones mate with each other.  Standard is grey.  The same size of any color will mate, IOW no problem plugging a grey into a red if they are the same size.

Polarity is marked on them for DC systems. they really are someones great idea-  I like them a lot.
If wired correctly it is impossible to reverse polarity plugging them into each other.

The links in jjkd's post detail the physical design, although I admit I've never seen the single pole ones wikipedia shows, all I've used have been 2 pole.

This is the voltmeter I used: http://www.amazon.com/dp/B005UWD2J4/

Originally posted by bcskimiller Thanks to everybody for the quick replies!  I think I'm taking all the parts I got at O'Rileys back and just ordering 4 of the Blue Sea Systems plugs.  May upgrade to the built in USB chargers once they get enough power to do the IPAD and these new fancy big screen phones; till then we'll stick with our cigarette lighter ones. One last (for now...) novice question: for the wiring, especially since I will have to run some of it under the trailer, is it worth paying for the outdoor/underground low voltage 12 guage 2 wire such as this:   http://www.amazon.com/Coleman-Cable-095136208-Lighting-100-Feet/dp/B002G9TND8/ref=cm_cr_pr_product_top   or will regular 12 guage 2 wire house stuff work?   Thanks Again!

In my last post to you I included 2 links, one for BlueSea and one for a USB adapter. The BlueSea sockets I used are just the cigarette plug connectors, no USB included. That gives you connectivity for all cigarette plug devices. The other link is to a USB adapter that plugs into the cigarette lighter socket and does provide 2 Amps for iPads etc. I'm a bit skeptical about the BlueSea built in USB sockets, if only for the replacement upon failure issues.

On the wire: The Coleman wire looks like it will be fine, but maybe longer than you'll need. I would use 12 Ga. wire available at auto stores plus the wire molds available from the same source, but you can do a cost comparison. The Coleman wire will work; don't use regular old house wire. For one thing, house wire is not rated for outside use. Secondly house wire is solid conductor, not stranded. Solid conductors are a lot harder to work with in cramped quarters like a trailer.
