GND output to injector.
Connect the other terminal of injector to switched +12V.
Example injector wiring for all of our ECUs.
Note: MaxxECU V1/RACE/PRO can handle 8A peak and 4A continuous on each output. MaxxECU STREET can handle 4A continuous.
MaxxECU V1/RACE/PRO has current regulation on all injector outputs to support peak-and-hold current type injectors (low impedance) directly.
MaxxECU STREET does not have built in current regulation and requires external resistors for protection when using low impedance injectors.
