Gurus,

I left my dump valve open for a day or two and I just realized that my dump valve solenoid is leaking air.

I just happen to have ordered a spare solenoid and have it...but it is a lot different than the old one.

Here is the old.  (Leaking from the exhaust valve)
   

Here is the new
   

My question is what do I do with the wires?   I assume the center air port is the supply and the other two go to the dump valve.  Is the thing on top for an air muffler?  Will the old ones just screw on or do I need to order a muffler?

Has anyone tackled the replacement and have experiences to share?

Also, I tried to manually push down the plunger of the valve but could not budge it. If I pull the air lines, will I be able to move it. (I need to close it so that I can make my way to the rally).
