Aux 9 & 10 and are available on the expansion connector and main header (purge for Aux 10) and can be used directly for E-Throttle control without requiring an external E-Throttle unit.

More than three Analog inputs are available on the expansion connectors which can be used to add TPS (Sub) and the APS inputs.

The SupraLink plugin doesn't have an E-Throttle relay setup and the E-Throttle power is supplied from the same source as the ECU power so an Aux will need to be assigned as the E-Throttle Relay but will have no effect on the operation of the E-Throttle.
