Thanks to all those who sent thier advice on my a/c system.  Turns out that 84/85's have completely different wiring of the a/c systems than the later models.  After studying the electral diagram for a couple hours, I finally decided to cut the red wire w/blue lead and eliminate the useless "compressor cut-out relay.  I will later install a commercial hi-lo pressure switch and connect the lo side to the compressor cut-out relay (the hi side will be wired in series the the lo cutout).  This will prevent compressor from sucking air in case of a leak and also prevent the discharge line from blowing (like in our tremendously hot summers).  I also converted the system to R134a.  Runs like a champ.
Does this sound like I'm on the right track?

Hey tomorrow's Friday, ain't it!!!!!
