I'm in the process of figuring all of it out. Coil should be here Thursday(4/3/14) so I'll let you know about the Thermocouple K status. As for wiring I'm going off what I've done previously and info I get.

so far I have found this which has helped - http://mediarealm.com.au/articles/2013/04/xlr-wiring-standard-3-pin-5-pin/

I'm not sure exactly sure how I should wire, but I'm sure if I do some more digging I can find out how.

And this is the XLR plug I got - http://www.amazon.com/gp/product/B00502CLRS/ref=pe_790750_114569500_em_1p_1_ti

I may go with this XLR plug next time - http://www.amazon.com/Neutrik-NC5MP-Chassis-Mount-Neutrik/dp/B00AELJ3ZI

Edit: OP posted this a while back - Dnail's XLRs are wired like this... pins 1 and 2 are power, 3 is TC+, 4 is TC-, 5 is ground. so I guess that's figured out somewhat.
