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