No problem just take a wire and hook it to your + battery cable at the starter and the + side of your coil. (if the battery and coil are the same voltage). If you have a 12V battery and a 6V coil you hook from the + battery cable to the ballast resistor.(That little ceramic thing with the 2 posts on it, hooked to your coil on the + terminal.) If you have a floor starter peddel you are done. (start the truck) If you have a key switch starter you now need to put the truck in neutral set the brake and hook another short wire from the + battery cable to the little post on the starter. Now don't freek out cause the starter will begin to turn as soon as you do that. So only hook it up at one end and simply touch it to the little post then remove it when you truck startes. Oh, because you are under the hood doing this you will need to choke it a little and pat the gas pedal before you hook up the starter wire. (Or what ever you have to do to start it cold normaly.)
PUT THE TRUCK IN NEUTRAL AND SET THE BRAKE!!!!!
