Exiting the back of the housing is a black cable containing 3 wires, Red, Black, & Green.
Red Wire- Connect to a +12v source. The fuse block is a good choice for this connection, a switched accessory fuse is a prime choice.
Black Wire-This is the ground connection for the module.
Green Wire-This is the tach input to the module. This can be either from the tach line of the engine computer or the switched side of an ignition coil.
Another black wire exits the module. It provides the connections for driving an external device from the window switch. (This wire is white on my module)
