Customer Question

I'm replacing an older WR 90-130 with a Honeywell R8285d. My problem is there are 2 wires off the bottom of the relay side which are 1 black and one yellow. There was a red on the WR which connected to a red wire in the ceiling and black which went elsewhere. I'm not sure which should connect to what on the Honeywell.

was the black wire on C and the yellow wire on Y or tied to a wire from thermostat that was on Y?
