That solenoid really is, sort of, a relay anyway. If you took the wire going to the horn itself (Y/Gr?) it's already gone through the trucks relay of course too.

Remember though, the Horn SW in the wheel is probably supplying Ground to that relay.

It really depends on the solenoid. The ones I use are air actuated so basically a few hundredths of a amp to control a really small solenoid that pushes a piston for a larger solenoid. Some larger solenoids require more current but most would hold up fine. Just check the requirements of the solenoid if your under 5a I doubt you would have any issues.

It says the solenoid current is 300 mils what does that mean?

It sounds like their saying it's 300 ma or milliamp in which case it's 0.3 a so you should be just fine.
