Two port, twin solenoid, Twin turbo connection Method (2)
(For obtaining maximum boost pressure on your twin turbo V configuration engine)

Port 1 of solenoid to Top port of wastegates
 Port 2 of solenoid to Pressure only source

Port 3 of solenoid to Bottom port of wastegates

Join the wires from both solenoids together (polarity not important) and then connect them to the brown and grey wires of the
wiring loom
Two port, single 4 port solenoid, single turbo connection Method (3)
(For obtaining a wide range of boost pressures e.g. 5 – 40 PSI. This connection method has varying degrees of success depending on
turbo system)

Port A of solenoid to Top port of wastegate

Port B of solenoid to Bottom port of wastegate
 EX port of solenoid vent to atmosphere

IN port of solenoid to Pressure only source
