L Series air susp compressor wiring ??

[steptoe]

These have four wires going to compressor unit, black & red seem to be pretty obviously power and earth for motor.

Do you know about the yellow and blue wires going to a sealed black box on comp unit ? Are they switch wires or do they need power also ?

ta,

UPDATE

I found both pairs need power and earth.

Also opened it up to find a broken magnet in the motor section, rust and corrosion throughout whole assembly. At least I know what to expect when I pull the other one out !!

thanks Fury - saved you the trouble
