( WELL HE'S RIGHT,..NOW ) WELL I NEED FROM THE CONDENCER TO THE COMPRESSOR AND WHERE EVER IT USED TO START FROM?...<table style="width:auto;"><tr><td><a href="http://picasaweb.google.com/lh/photo/Epn9i0u20ysz_skihL1QCg"><img src="http://lh6.ggpht.com/Snn1108/SPORnfVBOYI/AAAAAAAAAlg/-dVtit2e9E0/s800/100_0744B.JPG" /></a></td></tr><tr><td style="font-family:arial,sans-serif; font-size:11px; text-align:right">From <a href="http://picasaweb.google.com/Snn1108/302cid">302cid</a></td></tr></table>

OK, I have such a wiring harness in a box in my garage, I was hoping to install it (during
what is now referred to as "last summer") but didn't get to it. Regardless, your wiring looks
like this:



There's a black wire (A) that goes to the AC compressor. The other end goes to a gray,
2-wire connector (B) but I have no idea where that connector connects. IOW I don't know
where the other mate to that connector is, I figured it'd become obvious when I actually go
install this thing (I don't have AC in my truck so that wiring is unneeded by me).

Also coming out of (B) is a green wire which leads to a small harness that runs through
the firewall beneath the heater core & fan box. Coming out of that same small harness is
(C), a single wire that plugs into the resistor mounted in the above-mentioned box.

Hope this helps!

Your part b* should hook into something called a Pressure Switch by the looks of it. which is attatched to the accumaltor , it only allows the compressor to run if there is pressure with in the system.

Look at the connector that plugs into the compressor clutch. I believe it should have a diode wired across it to clamp the kickback voltage from the clutch windings.

Would (NumberJunkie) have a part number for this?
I need from the green plug on to the compressor.

Sam, see if you got e-mail from me; if not, write me at
ctubutis -at- yahoo -dot- com. You're apparently set up
to not allow forum members to send you e-mail messages
