Tech | Conversion Wiring Install
For those of us who’ve been around the block a few times I’m sure you remember hearing about the first 5.0L EFI Mustang engine swap into a classic Mustang. Maybe it was in your favorite magazine, or perhaps you walked by a nice Mustang at a show and had to do a double take when you looked to see what was under the hood. Regardless of where or when you first saw this swap, probably the first question you had in your mind was “how hard was it to do?”, followed quickly by “I wonder how much it cost?” Well, depending upon when you saw your first 5.0L EFI engine swap the answers could be “it was a pain in the butt” or “it was as simple as plugging in a few wires.” Reason being, early adopters always have it rougher. These fanatics go on a fact-finding mission, tearing into the project with abandon, buying up wiring diagrams and learning how every little subsystem works. So if you saw your first 5.0 EFI swap 15 years ago, it meant it took that owner a lot of trial and error, custom wiring, and fabrication of parts. Today it’s mostly a matter of which company do you want to buy your conversion wiring harness from (there are at least four that we know of) and how you’ll setup your fuel system. Yes, it has become that easy to install a 5.0L EFI engine into your Mustang or other classic Ford. Hell, there are whole companies that survive off of manufacturing swap parts and doing the conversions.inline_mediumwraptextrightThe 4.6L Three-Valve Control Pack, shown here, includes a custom-calibrated PCM, a chassis side harness (you reuse your engine side harness), Ford Racing cold air induction kit, ETC throttle pedal, Ford Racing mini power distribution block (PDB), a mass-air meter, and new oxygen sensors. The 5.4L Four-Valve kit also adds supercharger-specific cooling hoses and fittings as well.28089916/techarticles/mdmp_1004_modular_engine_swap_wiringmdmp_1004_01_+control_pack_chassis_harness+three_valve_control_pack.jpgTrue

Whether you’re restoring a classic Mustang, building a restomod full of modern technology, or assembling a Factory Five Roadster, you’ll have to make some important decisions about the wiring in your project. Wiring can be one of the most complicated jobs encountered during the course of an automotive restoration or custom build. It requires the careful routing of numerous control wires and power leads to and from switches, and the various other electrical components within the chassis and body. The wires are bundled into cables that must be carefully hidden to achieve a clean and sanitary looking installation. On a restoration project, sometimes the factory harness will be serviceable and sometimes it will not, while those starting from scratch are doing just that. Before you go forward with the electrical aspect of your next project, you should be aware that a new choice for vehicle wiring exists in the form of the Littelfuse ISIS Intelligent Multiplex Wiring System. The ISIS arrangement is a modular micro-controller-based automobile electrical system than can replace or augment a conventional wiring harness. It uses a centralized command or “hub-and-spoke” arrangement to greatly simplify electrical wiring projects.
