Now that you mention the "all trucks have a foot starter" part I found the small patch they put in place of the original switch. I went and looked through the assembly manual and found the starter switch assembly and given all the parts I don't have I am guessing unless I was able to find a foot starter assembly used I'm better off going with a standard universal ignition.
My starter sits on the passenger side of the engine, but is wired straight to that button on the dash, which was wired to the ignition. Am I basically setup (at present) to have a standard non-foot starter ignition then?
