Come on move that AC line while you’re at it!
Early summer. There is an order of operations to this!

Those battery cables look sad
They sure do! It's time to do something about them.
Make sure you run your York’s pressure switch off a relay to not pull a few amps through the pressure switch.
How many amps does the pulley clutch draw? The pressure switch has been between the relay and clutch for years.
Over 3 amps but that doesn’t account for the spike of current when it engages. It’s proven difficult to get a quality pressure switch anymore, I wouldn’t want to run 3+ amps through one.
Run your switch pro power wire to both pins 30 and 86 of the relay.
Run pin 87 to the york clutch.
Run pin 85 to the pressure switch with the other terminal off the pressure switch going to ground.
This simplifies the wiring using a switch pro and a relay to get the pressure switch on the low current side of the relay.
Have fun trusting the Chinese.
For the last 7+ years I didn't know I had a problem to solve until 15 minutes ago.
What side of the relay is your pressure switch on?
Highlines are really great!
Three days of struggling and I finally figured out a mount for half of my Cadillac horns!
four note GM horns are four times gooder then a Jeep horn
I love the sound of those train horns.
In the olden days, fire trucks ran what is called a stutter horn. They don't have a compressed air tank. What they use instead are stupidly high volume direct pump compressors that go directly to the air horns with large bore air line to deliver the high volume. Each horn has its own compressor with a motor about the size of what a winch uses. They are stupid loud, and very attention getting with that very annoying stutter tone unique in this area to fire trucks. When I worked at the ambulance company, the owner gave me a couple that had quit working. A bit of work got them to work like new and my buddy wanted them for his truck, so we did. That lasted for all of a one time use. Some ass cut him off on the freeway, he got on the horns and scared the idiot off onto the shoulder and into the ice plant out of control. That scared my buddy so badly he never used them again for that.
Had to look it up
I've been around enough folks that I learned very quickly not to brag much in their presence. I was telling my buddy about the stutter horns. He told me to hold on a second, walked over to his monster air compressor (3 phase and very large) fired it up, when it got to a full tank, he hit the valve handle on the wall. Fucker had a ship's horn mounted out back. He ran a 1" line to it and it kicked the compressor on in about 1 second. The air consumption was well over a 100 CFM to fire that thing off.
The bell was about 20-24" across and it was about 5 feet long. Roughly similar to this one.

Okay, you win.
