I just replaced the sequencer for this heat pump. Did not take a photo of wires before switching to new sequencer. Does anyone have a photo or diagram of how this wires up? I think one of the small wires went to the wrong spot. Please help.

Thank you for quick reply. Very kind. Unfortunately they do not seem to have it.
Any other suggestions ? It is cold.

Are any of these similar to the sequencer on your unit? Each "layer" of the sequencer is a switch, the bottom is the low-voltage input, so this may not be too difficult to figure out, even without a diagram.

This may be of help. It says for Carrier blower adapter BUT the furnace wiring is for the Coleman 3400/3500 series
