5.9 EFI Swap

thats the thing to do use as much as you can from the donor. you have to replace things like your temp sensor and oil pressure sensor withe the older oil sending unit and tempurature sending unit to make your factory gauges work. all a piece of cake. after you get it up and running then we can hook up the diagnostic port. but for now just those three wires from the bulkhead connector. the rest of the wiring stays the same to run your lights ect. an important thing to remember is to make sure you have your block ground connected. i left this off on the first magnum swap. and i went nuts thinking i did something majorly wrong. get this done then you can advance to the new hemi.
