This thing only has 4 wires- not the 5/6 you
describe.
Two must be grounds- as my ohm meter says they go to
the metal case of the compressor (chassis ground?).
Then there is a plug/connector harness on the side
with two wires attached to it- one red, and one white
(or yellow- hard to tell).
Could it be that one ground and positive are for the
compressor, and one positive and ground are for the
release valve? This unit appears to have a resonator-
looks like those collector cans you can get for
aftermarket horns/sirens...
No other wires on the thing. There appears to be 3
places for hosing to hook up- so perhaps one
pressureized/compressed line for front, rear, and then
a vent???
