Well it should go

Red-RH with jumper to RC

White-W1 or AUX

Orange-O/B

Green-G

Yellow-Y1

Light Blue- This could be C but that would be hard to say 100% you would have to go to the board inside the furnace or air handler to check where light blue is connected to to know for sure.

All I ask is please select the 5 STAR rating at the top of your page before leaving otherwise I receive ZERO credit for assisting you. BONUSES are always appreciated...Thanks and you can come back anytime for free followup questions & Happy Holidays!
