Internal wastegates with 2 ports
 Port (1): vents pressure from the solenoid.

Port (2): connect to one of the ports of the actuator

Port (3): to pressure only source

Block off unused port on the actuator with suitable blank
Single solenoid, twin parallel turbocharger hook up
(For straight configuration twin parallel turbocharger engines E.g. RB26DETT)
 The e-Boost2 is capable of controlling twin internal wastegate turbochargers with a single solenoid.
 This method is used when the turbochargers are mounted close to each other allowing the solenoid to be mounted close to both
actuators
 Each solenoid port is connected as follows:
Port (1): vents pressure from the solenoid. Connect this hose to the intake side of the turbo, between the air cleaner and the inlet of the
turbocharger. Otherwise connect a short piece of the silicon hose and face the vent downwards to stop water or debris entering the
solenoid.
Port (2): to tee piece that feeds both actuators
Port (3): to pressure only source
Twin solenoid, twin parallel turbocharger hook up
(For V configuration twin parallel turbocharger engines E.g. V6, V8 etc)
 The e-Boost2 is capable of controlling two solenoids for twin parallel turbocharger setups.
 This method is used when there is a great distance between the wastegates. This allows the solenoids to be mounted close to the
wastegates to minimise the length of hose used and to maximise response
 You will need a second solenoid for this method (TS-0301-3003)
 Connect the grey wire from the e-Boost wiring loom to one of the wire from each solenoid.

Connect the brown wire from the e-Boost wiring loom to the remaining wire from each solenoid.
