I bought a wrecked 2012 F150 with the 5.0 Coyote to use as a donor for my 1979 F350 crew cab. It was hit hard in the left front wheel shoving the floor back far enough that the brake and accelerator pedals were against the floor. I have repaired the visible wiring damage and checked all the fuses etc. I see no reason that it wont crank. The instrument cluster won't power up and starter won't engage. Is there something similar to the old school fuel pump inertia switch that kills power to the fuel pump and main electrical system? This truck should run. Any input? Thanks

 

That will have an inertia switch, but I think all that does is keep the fuel pump shut off, doesn't affect electrical.

Will it crank if you run 12 volts direct to the starter?

 

there are two dash harness connectors that will physically plug into the same spot on the cluster. Make sure you're using the right one
