Constructing a custom loom to match application perfectly.

Injector output power circuit in this application will be fused at 5 amps. Fuse best placed to protect FET's rated at ~7amps continuous.

I have calculated the 'worst case scenario' loading for the injector outputs should they all be 'ON' (unlikely) using the coil resistance of the solenoids and injectors.

*4x injectors at 14ohm

*1x boost solenoid at 27ohm

*1x Emissions purge solenoid at 24ohm

**The resulting parallel circuit resistance is 2.77ohm

**The resulting current draw in worst case is 14.5/2.77=5.3 amps

Ignition 10amps (if not less?) appropriate for 4x COP's? *The Toyota Yaris coils are often used to upgrade a wasted spark coil pack on the Mitsubishi Evo's and they use the original coil wiring which is fused at 10amps.

*Not having probed the coils, 10amps seems reasonable since that is what I used previously with wasted spark coil pack and Desno inductive COP's.

WBO2 heater circuit suggested fuse rating of 5amps.
