Customer Question

Hello. I have replace 3 relays 18k6901
3 sequencers 72f83
I need help to wire it back up i jave a wiring harness
Red to c
Orange to W2
Yellow to W1
Black splits to relay 67k65 and to transformer
Red splits to fan and transformer
Brown goes to relay 67k65
It also has a large gauge black wire and red wire that go to the fuse box
I know that the first sequencer has the relay to the middle the fan to the other middle a wire from the bottom opposite side to the bottom opposite side to the second sequencer. I think the brown (relay) goes to the top of the first sequencer and i need power so I have a loose Black wire that has a clip on one side so that can go on the ofthe top opposite of the fan. I have 3 more heavy guage black wire that has a clip on one side and the other goes to the fuse. I assime two of them go on the top of the other sequencers for power. I dont know what the last one is for. I have six short wires that have clips on each side and connect everything t

hello,

I saw your question has not been answered. I think it is because there is no model number for the furnace...and this can change the relay wiring....can you supply the model number of the unit itself?
