Anyone have the wiring schematic? Where do the yellow and grey wires go?

Sorry for the "dumb" question. Just got a used one w/o instructions.

Thanks in advance.

 

if it is the same as the msd then you hook the yellow one up to the white or ground on your relay. and your grey one is not used. but that is just what is know for the msd not sure if it is the same but seems like they should. aslo there is a wiring schematic in one of the post that was done like yesterday that is really good.
