FiTech EFI system

Yes, our Cuda did the same as yours. Run, then stop, maybe start and run a bit and then nothing. Six pin connector fried. This was a 2016 throttle body and FCC. The FCC connector had fried 1 1/2 years ago. I jumped the orange FCC wire around the connector and it worked unit a couple of months ago when the red power wire fried. FiTech stepped up and replaced the ECU, and wiring with the newer harness (with separate power and FCC wire harness with 14 gauge wiring) FREE OF CHARGE! This unit has been out of warranty for over a year! Bryce in FiTech's tech department really helped out. I still have concerns about the FCC v1 and its reliability. In the process of installing the updated throttle body and rewiring a couple of things due to the new harness. Debating on whether I should run the new 14 gauge FCC orange wire directly to the pump as before or run it through a relay.

If you run it through a standard relay remember to set the PWM for the pump to 100. Otherwise you’ll need a solid state relay that is compatible with pwm.
