I need to hook up a new programmable t-stat to an older mobile home with only two wires coming out of furnace. I need help!

Exactly correct. Same setup I have on the old mobile home at camp.

I can the t-stat to come on if I hook the red wire to R and the white wire to C. The rest of the spots are: W1/O/B, Y1, G, MISC2, CK1 CHK GND
