Look Sprintgeek
I am not HVAC man but you got to admit
you have screwed up royally before you have remove
old unit you should have take pencil and paper check
what each wire activates and market down
at present no-one can tell you what goes away
because in most cases color code does not apply
so how can any one gave you right info.
it would be beyond me who ever you get to
fix your problem he will need to trace wires
were to what are hook up befor hooking Tst.in
lots luck.
Tony
