FFG Coyote Godzilla ECU Mounting Box

Modern power. Nowhere to put the computer. Every classic truck swap runs into the same wall. The engine goes in; the harness comes out; and then there is a brick of electronics with no home and a clean engine bay to protect. Zip ties and a makeshift bracket will hold long enough to fire the truck up. They will not survive the miles ahead; heat; vibration and road spray all find a loose ECU eventually. This box turns that problem into a finished detail. Laser-cut aluminum with a heat-resistant black coating that disappears into the engine bay while it keeps the elements off the computer. On a 1973-79 Ford pickup with stock inner fenders it bolts straight up; no fabrication; basic hand tools. Choose the box for your engine generation - Gen 1; Gen 2; Gen 3 through 4X; the 1973-79 specific Gen 3 through 4X version; or Godzilla.

  • The ECU stops being an eyesore - a finished aluminum box instead of a computer zip tied to a brake line.
  • Heat and spray stay outside - the black coating is built for engine bay duty and the box keeps the elements off the electronics.
  • Bolts to what is already there - stock inner fender attachment points on a 1973-79 Ford pickup; no drilling and no fabrication.
  • Cut for your generation - Gen 1; Gen 2; Gen 3 through 4X and Godzilla each get their own box.
  • Laser-cut; not bent by eye - the panels line up because they were cut to the same file every time.
