There is no arrow on the valve body, as referred to in the web page instructions. So which is inlet, which is outlet?

It’s shown in the pics on the solenoid Amazon page https://m.media-amazon.com/images/I/61gDjT+q6jL._AC_SX679_.jpg

can it be changed to normllay open?

No it cannot be changed. I would not purchase this unit anyway, I bought 3 and 2 failed within a couple of months.... poor manufacturing quality where the plunger seats on the valve... .

How water proof are these units ? Can they be mounted out of the engine compartment, under the truck bed ? Thanks.

Not water proof Works as no or nc

On a 220 v switch does the two red wires on the switch go to the same 220 v power sorce

No, Each wire should land on its own feed.. a breaker for 220 has two terminals. Not knowing what you are connecting they are multiple options but the two wires would not land on the same terminal.

Easy to use and works like a charm

Hooked this between my compressor and my laser engraver to control the air flow to the nozzle - worked first time and simple to intstall the wiring. Works like a charm.
