I have a Trane XE1000. I lifted the top off the unit and accidentally disconnected the fan wires from the unit; brown, black and purple. Where do I reconnect these wires to get the fan working.

Thanks in advance for your help.

That takes some serious work to get all three to pop off.

Brown to run cap

Purp and bk to line voltatge (contactor)
Or one to contactor and one to defrost board if a heat pump
One to
