a complete newb with wiring

before I start I am very new to this and have researched but just become more confused... I'm wanting to do a few thing. 1)I have compressors in my truck and want remote LED's to turn on when the compressors turn on (so I know twhen they are running) 2) I have a solenoid from the air tank that control my train horns, I want to hook up a push button switch, and when I hit the button I want to see another LED light up There is a few other things I want to do with rocker switches as well but I think answering these two questions will help. Basically My rockers are going to be in a remote rockers are going to be in my glove box and I would like to run my indicator LED's somwhere on the dash board. I truly appreciate all the help!!!

Do you already have a switch for the horns?

No I don't, I'm looking for a momentary hand grip one where you push it in with your thumb, like a grip.

This should work for your second question. For your first question you will need to locate a wire that is energized only while the pump is on.

The led will not allow enough current for the solenoid to engage.  The positive leg of the LED needs to be connected to the same side of the switch as the solenoid.  If it is a 12Volt Led, simply ground the other leg of it.  If it is a voltage other than 12V you will need to insert a 470 ohm resistor between the negative lead and ground.  I will draw a pic this evening if needed.

right my bad... it was really early. lol
