Emglo double stack compressor wiring

[Manns50]

I have an Emglo, 1.5 hp double stack tank portable compressor. Older unit but works great. Was changing the switch and like an idiot forgot to snap a picture of the wires before removing it. Trying to save myself some time not have to remove the compressor to access the wire colors/connections. Is there a way to ohm out the wires to determine polarity?
If I have to, I’ll remove the compressor in order to access the wire connections, but figured there might be an easier way?

Wire colors

There is no polarity. Brown and blue are L1 and L2

Great, you’re pretty certain of the wire colors?
Thank you!

the important thing is to locate the line & load on the right terminals of the switch . they are marked line & load or line & motor or something like that

I am certain Blue and Brown are the power wires. On an AC motor like this, there is no polarity. Blue and Brown are effectively interchangeable.

The Green/Yellow wire is ground.

Yes I knew the A/C wiring did not matter other than the motor turning in reverse depending how the motor is setup but I wasn't sure on the earth ground. Thank you very much for your time. This forum is super helpful.

Yep for sure, was going to make sure I had that correct, have rewired the line side of this before but had never removed the load wires or changed the switch till now. You all rock...very helpful thank you!
