How to Wire the Dash in a Triple E Motor Home

Triple E motor homes are recreational vehicles (RVs). These motor homes are built onto the Ford E-450 chassis. The Ford E-450 features a 305 horsepower, 6.8 liter, V-10 engine with 420 foot pounds of torque. The dash, or instrument panel, in the Triple E, or F-450 cab, is important because all essential gauges like the gas gauge, tachometer and speedometer are located there. If the dash panel lights stop working, or if a gauge stops working, it is important to rewire them so that they function properly.

Instructions

    • 1

      Test the dash, or instrument panel lights and gauges, to determine what is and what isn't working.

    • 2

      Locate the fuse box on the lower dash panel to the left of the steering wheel. Take off the fuse cover by hand. Examine the fuse diagram on the inside of the lid and inspect the fuses that control various gauges within the instrument panel. Replace any fuses that appear blown. Pull out the bad fuses (if there are any) with needle-nose pliers and slide replacement fuses in.

    • 3

      Pop the hood of the vehicle and remove the negative battery cable with the adjustable wrench.

    • 4

      Lower the steering wheel as low as it will go by pulling in on the steering lever and pushing the column down.

    • 5

      Remove the screws holding the RV's instrument panel in place and set them aside. Carefully pull the instrument panel forward.

    • 6

      Examine the backs of the gauges to make sure all connections are intact. If any gauges are unplugged, plug them in. Unplug and replug in the main electric wiring harness.

    • 7

      Remove any burned dash panel lights by twisting them to the left and pulling them out. Install new bulbs, if need be, by twisting them to the right until they lock in place.

    • 8

      Slide the dash panel back into place. Insert the retaining screws.

    • 9

      Replace the RV's negative battery cable and then test the dash panel.
