Re: A/C CLUTCH SOLENOID
Your use of the word common confuses me, as it is the term we use
for the white wire in out homes which is grounded, just like the bare
copper wire is.

JEEPR did pass the time by typing:
> OK done some reverse engineering
Did you read the schematic I posted a link to?
The relay is supplied 12V from the battery through a fuse
to the relay coil. The relay coil then gets it's ground
through the computer. That clicks the relay.
The 12V supply to the clutch runs across the high and
low pressure safety switches to the relay (switch side)
and then to the clutch.
