what are your plans for the truck? daily driver or monster truck? how much of a project are you looking for? this particular truck is a 2.5l/auto and will be the opposite of speedy, which will get worse with bigger tires. and "wiring issues" could mean a couple bad grounds, or it could be that a mouse made a home inside the dash and you need to rewire most of it. can't say without checking it out in person. if you go see it, be sure to bring a fridge magnet and check for hidden bondo and rust. pull up the carpet and look for moisture underneath which could indicate rust.
