I got a solenoid to operate a Grover air horn and I'm unsure how to wire it. The solenoid has two terminals and I want to use the standard Land Cruiser horn wire to activate it. Any ideas on how to wire this up?

Positive and negative maybe?
Doubt the solenoid will be polarized, would be marked if it was. Just hook the wires up if yours has two wires(don't know US setup) if not you will need to connect the second terminal to earth.
Just had a thought what current does the solenoid need to open? You may need a relay.
Ground one terminal and run the wire from the factory horn to the other. The factory setup gets it's ground from the base of the horn so either wire at the horns is +12v.

Sometimes the solenoid is directional (ie. the air goes through in one particular direction). Look to see if there is a small arrow moulded on the air-part of the solenoid.
The solenoid I used to hook up my hornblasters-style train horns *was* directional.
