Solenoid valve has two ports labeled 1 and 2. Assume air into "1", outta "2" ??? What size are the fittings for these??

id go look but its freakin pouring rain:flipoff2: !! are you referring to the nylon tubing "fittings"?

I dont think it matterss......

1/8 pipe into the solenoid

It dose mater one side vents when the soleniod is closed and as for the fitting I believe they are a metric thread and you will have to get the ARB adaptor to go to 1/8 pipe I don't remember which is side one or two but if you blow into one and it blows through that is the side to the locker.

Air supply goes to 1, locker goes to 2.

the solenoid body is 1/8" (british) BSPT.

The body of the solenoid is soft and you can thread in a 1/8" NPT nipple. (that's what I did) and if you are using blue line, use the ARB fitting on the locker side.

I scanned the install sheet a while back and its got some pics, and if you need them, and some ARB part numbers for the british stuff.
