No problem. I have a defroster switch that i am going to use to activate it and a pressure switch to turn off/on based on pressure in the tank. I have a couple wiring diagrams courtesy of MUD i can share.

There was a nice wiring diagram made by Sun Performance Products for their Quickair2 air compressors that used to be on the 'net. Follow that particular wiring diagram and use a switch with a built in light. When you use this combo, the light in the switch tells you when the system is either full of air or it needs air.
So, here's how it works:
- turn on the switch. If the air is more than your minimum cut in pressure (usually 85 psi or so), the light stays off.
- as you're using the air in your OBA, when the air pressure in the system falls below your cut in pressure (85psi), the York clutch coil is energized and the light in the switch turns on.
- when the air pressure in the OBA is above the cut out pressure (usually 110psi), the light shuts off and the York clutch coil is de-energized.
This is a slick and clean way to know when your system is running w/o the need for an in cab air pressure gauge. I'm using a pressure switch with the following rating: 85pis/110psi
I'll see if I have a hard copy of this diagram.

Tensioner
To ensure that tensioner bolt remained in place, I added washers top and bottom and double nuts(Jammed) at the bottom.

Nice job. That puppy gets a bit on the heavy side! If you remove the clutch pulley from the unit, it becomes MUCH easier to handle.

Alia176, that is a great idea. Gripping this thing is difficultat best. Whenever there is a aluminum head and steel bolts, you have to be extra carefull
Not to thread jack, b ut a few in here have asked where they can get a bracket:

I finally got the compressor mounted. In the process I dropped one of the washers for the idler pulley. Since i am traveling this week to NC, i will finish up things next weekend.
So, quick question, for those of you with forced induction, what are the options for OBA? I prefer engine-driven vs electric, if possible. co2 hasn't even entered my mind

If you have an SC you only have electric and CO2 options left. There is only one place to mount the York, or York-style compressor, and the SC takes that space.

Couldn't you remove the stock ac compressor and fab a bracket for a York there? You wouldn't have AC anymore. I think with an SC your better off with a 12v system though. The Puma's are hard to find but I hear they're great. And you can use them with any vehicle.

If you went that route, there are companies out there that use other compressors, similar to the one that is on the LC*80, for their OBA set up.

Idler Pulley
I will need to source a new tensioner pulley. It seems that the back washer diappeared in my garage

I was afraid of that. I don't have a s/c yet, but it's on the dreamlist. That's also why a small turbo setup also crossed my mind.
I haven't looked under the hood of a s/c 80, but I was hoping that there would be space somewhere for a compressor. Preferably a York, but a rotary would work fine. I can deal with the oiling issues, it's not that bad.
Ahh, I won't delete the a/c on my 80. I did do that on my 85 pickup truck, using the stock rotary type compressor as an OBA compressor. It worked very well, but I'm too fond of the a/c on my 80.
So many projects, so little time and money. Haha.

I know what you're saying. Hopefully I don't have to pay too much in taxes this year and I can actually get a start on my axle rebuild.

Puma's are usually easy to find at <www.buzzardgulch.com>, or Ebay/Amazon. Copper State Cruiser members in Arizona are running nearly a dozen of them with no problems so far. We even have custom mounting brackets for the 80's. John
