Here's a very rudimentary wiring diagram that I put together. The wiring seemed pretty simple. The ground wires are hooked up identically to the white whires - twisted together.
I guess the thing that has me most concerned is that I did try to install a simple non-programmable 4-pole t-stat. It was a Honeywell model CT410B. It had connections for two black leads and two red leads, so I just connected each of the loose blacks to one of the black leads and connected the two reds together - same as the old model. Initially it seemed to work but then the next day the breaker kept blowing. I removed it and reinstalled the old one and the breaker stopped blowing so I figured that I must be doing something wrong.
