Does yours have the control board or has it been converted to the relay system.Need to know so you get the correct print.

Ed welcome to the Stak. As Billy mentioned we need to know if on the unit on the control box is there a wiring diagram number stenciled on the side of the box? Do all the wires that connect in the control box connect to a printed circuit board or are there relays inside. Im posting your build sheet and the wiring diagram for the one that's supposed to be there.

Hi Billy, mine has a control board, what if I by-pass a portion of the board in order to get this her running? Thanks for your help/ Ed
