is this product compatible with harbor freight central pneu #69783 9gal 212cc 135psi wheel barrow compressor

You'll need to turn the pressure down pretty low as it's is factory set to 175psi. As long as the cable is long enough it should be fine.

Is there an outlet for a regulator and pressure switch

yes. you would have to add a tee fitting to install a regulator or pressure switch. this is an unloader valve. it regulates to the max psi your compressor will put out.

I'm building a custom compressor that will be electric. Will I be able to use this unloader on an electric compressor?

Wouldn't you want one to shut you electric motor off? This will not do that,you need a electric cut off switch,this would work just to unload compressor but not shut motor off

Great fit for air compressor

Just what I needed to get my gas powered air compressor. I been using my air compressor quite a lot since my battery powered impacts have broken. I replaced my broken valve with this one and it has been working great

Worked pretty well, but after a few cycles

Worked pretty well, but after a few cycles, it started cutting out at 170 psi instead of 175. It also leaks a bit of air.
