Chris: Those XRC connectors are pretty cool. Looks like mouser sells them for $18 per side - $36 a set. Still pricey as I'll need 6 sets, but they are totally water/moisture proof. I'll have to see if I can source them locally...
Kevin: Most of my LED's are the XT-E's so they can go to 1.5A but the LDD should limit them to just over 900mA. The XM-L's however could be driven to 3A. I doubt I'd ever run them that high (probably boil the water, lol) so I maybe over thinking the whole connector issue anyway. I wish I could find something like the DB25 that could take 1A per pin...

Do you guys know anything about these aviation style connectors?
 Is that the mounting base that would screw to a dash AND the cable connector that would plug into it?

If looking locally.... try checking with a place, or electrician that does industrial control systems/automation, they might have something.

I've been watching some similar connectors on eBay, much less money & available in different pin configs. Probably not the same quality, but will likely do the trick.

Essentially it's mil spec connector knock off. Here's a link for everyone's info to one of the big players in the connector business, Amphenol. There are a few other big boys, ITT Cannon, Bendix, but all these products will be all very pricey & probably overkill for our intended use. http://www.amphenol-aerospace.com/pdf/12-090.pdf

So, I'm having an argument with myself about wire sizing. And as the internet would have it, I'm getting conflicting info.
According to this chart 18AWG can take 10A (which I actually find a bit hard to believe): http://wiki.xtronics.com/index.php/Wire-Gauge_Ampacity But according to this chart it can take only 2.3A (which is one the other end of the spectrum): http://www.powerstream.com/Wire_Size.htm Anyone have any info on sizing wire for 1.5A running 10' while bundled?

Well, I had a good talk with an electrician that I use and he helped me wade through some of the dilemma's I've had. He's not a electronics guy, just a sparky who does house and commercial wiring but his code book pointed us in the direction I think I needed. Turns out a 18AWG wire all by itself in the open air can carry 10A but it's de-rated once it's bundled with a bunch of others. The ratio of decreased carrying capacity depends on how many wires it's run with. But according to our math 18AWG should be fine for what I'm doing. And as it turns out he had a roll of 18/21 sitting in his shop he gave me for $2/ft. It is fire alarm wiring.
 And I also got some other goodies in the mail yesterday. Now all I have to do is figure out how it works
