This is the Moddbox PLX to SCT Firewire. This cable connects any X3 or X4 SCT device directly to any PLX module. This cable is fitted with two PLX compatible plugs so you can log up to two (2) PLX module analog signals at the same time using your SCT device. The analog wires come pre-soldered to Molex compatible push connectors.
This cable is essential when logging/tuning your vehicle using SCT and PLX. Just connect your PLX device to your SCT flash unit and start logging. Simple :)
