how should you hook up wires to seleniod. ???

You can tell by the size of the connector rings, the biggest one is the battery, it goes on the largest screw, the others have plugs or small ring connector that would trigger the solenoid, that goes on the small screw

Here's a picture of what it looks like. Good luck!...http://www.justanswer.com/car/6c762-suzuki-xl7-every-wiring- diagram-find-2003-suzuki.html
