Motor wiring. My Vax VS19TL motor died and I have managed to get hold of a new Vax 006 Turboforce

Question

My Vax VS19TL motor died and I have managed to get hold of a new Vax 006 Turboforce motor which is the same size . My problem is that the original motor had two wires (black and white) which ran to the PCB switch. The new motor has three wires (black, white and yellow). I have ordered the PCB wiring loom for the 006 motor but I can't find any documentation that tells me where each wire goes. Can anyone help?
