Update.
Compressor works without starter box. I had a "doh!" moment when looking at my cousins IR compressor that is identical to mine.

He pointed out that his has start and run capacitors with a pressure switch rated to take the 15amp kick at first start up.

I get home, see that mine too has start and run capacitors. Cleaned the dirt off the pressure switch label, and read that it's also rated for 15amps. Wired that sucker direct to the switch and it fired off! I don't even care at this point how long it took to figure all this out. Just glad to finally have compressed air.

Jory, I printed out your schematic and placed it in the starter box. Might just need it one day. Thanks for the insight.
