About 8 months ago my daughter's Payne PF1MNB036000AAAAA air handler quit working. The blower would not come on. I decided that it needed a new board so since she needed heat I disconnected the blower leads, one yellow and one blue and attached a cord to it to provide 110vac power to the blower making it run all the time. I then ordered a new board.

I have just now got around to putting in the new board but forgot where I disconnected the yellow and blue motor leads (have female disconnects). I think the blue one attaches to the black relay on the board but I can't figure out where the yellow one clips onto a male connector. Help, please.

Blue is a speed tap and yellow is common or L2 There should also be a red and black wire coming from the motor that should be capped off unless the motor has been changed. A picture of the board and wiring diagram would help. It looks from the very poor wiring diagram I found that the yellow wire would go to K1 and the blue would go to NO but like I said the diagram wasn’t very specific.
