My thermostat wiring is y g r o w2 e c .the new wiring is c g y o/b rc r aux e l . Can someone tell me how to wire it. I'm trying to wire in a honeywell digital thermostat. Model rth7400 my current therm is a nordyne 914832. Please help

Y to Y, C to C, R to R or RC keep the jumper in place, G to G, O to O/B make sure T-stat will energise reversing valve in cooling mode, W to AUX, E to E. You will not use the L circuit. Good luck
