From what I can remember, it's a simple 2 wire solenoid.. That being the case, they should be connected to the # 1 & 2 wires of the motor relay output side M1,M2. If it was wired for 480, then the coil is connected to the #4 and #5 for example. That will get half the voltage when the motor operates. Standard for AC motors with add on brake on the back..
