Not sure if you are talking about the low voltage wires (24v) , if you are red should come from transformer ,(R) term, then the Green wire should go to blower relay, White should be for your heater sequencer . Not sure about your gray wire. Also you should have a common wire (from the other side of transformer ). Try to call a dealer , they may have access to the wiring sematic. Hopefully this will help you out.
