I am currently wiring the 53 that I am restoring. Follow along and I will show you how I do it. You will need a good set of crimpers, electrical tape....several rolls, heat shrink tubing, multiple styles of fork, bullet, and slip connectors, LOTS of zip ties, A few books.... Solder and soldering iron. Also, have your chiropractor on speed dial. Some of you may need some installer lubrication, choose beverage of choice, but I highly reccomend going easy on the leaded variety. Also, colorful language is shure to be employed, so clear the area of small children, church members, and ALL preachers, though you may need some prayers from them later. First, strip the dash of trim and guages, and all old wiring. I am wiring this one as close to stock as possible. This will require some changes in the harness. Now lets open the box. This came from E Z Wire. Spread your harness out on the floor and see what you have. The harness is bundled prety well with like wires, but now you need to do some bench work. Pull out unused wires (oil press. sender, temp sender, tach, turn signal indicators..they are included in the signal stat 900 in the truck, etc.) Keep these wires in case you need to add a wire or 2 for accessories. Keep your bundles straight and re zip tie them as you finish with each. These are the wires I removed. Lets mount the fuse panel. Find an out of the way spot under the driver's side of the dash. Make shure you are low enough that you screw into double wall metal, not directly into the outer body! Begin pulling wires to their approximate locations to get them organized and out of the way. Pull the wires through the factory harness hole. These are the engine, front lighting, horn, rear harness, starter wires, brake switch, alternator power exciter wires.( THis truck is running the generator, but run the alternator wires in case it is converted in the future. Now pull the wires through the grommet. ALWAYS use a grommet when pulling wires through a hole in sheet metal. When the bundle gets thick, you may need to slick them up to get the last ones through. I used white lithium grease. Slide the grommet up the bundle of wires to it's home in the firewall. Begin running the wires to their places under hood.
