I have an intertherm furnace. Someone cut out all the wiring hook-ups for the thermostat and fan, and the outdoor unit. Does anyone know how (or where) to put the wires to get everything working?

Just the low voltage t-stat wire? Are there any parts missing? Is the 110 volt hooked up?

Everything is there but terminal block. Not sure how to put wires together to make everything work in proper sequence

Is it a electric furnace, or gas?

Electric

I also found its old switching box. But I still can't find the thermostat hook up. How would I put the thermostat wires. I have (r) (w) (y) (g) coming down from thermostat. (r) (b) from transformer, (r) (w) from outide unit. The switch box has (r) (b) low voltage, and (w) (g) high voltage coming out. I'm lost as to where to hook up what. I have a little experience, but not enough to follow this chop shop job. Thanks for your help

Are you trying to get the ac to work or the heat? Or both. If you have not termanal block then you may not have the ac relay either.

Trying to get both to work. I have a full array of sequencers and switches
