Two port, single solenoid, twin turbo connection Method (1)
(For controlling boost on a twin turbo, twin wastegate, single solenoid turbo system, on a straight configuration engine with high back
pressure)
Connect the bottom port of the wastegates and Port 1 of the solenoid to a Pressure only source via tee pieces
Port 2 of the solenoid to the top port of the wastegates via tee pieces
Port 3 of solenoid vent to atmosphere
Block off other turbocharger pressure port (if needed)
Two port, twin solenoid, twin turbo connection Method (1)
(For controlling boost on a
twin turbo, twin wastegate, twin solenoid turbo system, on a V configuration engine with high back pressure)
Connect the bottom port of the wastegate and Port 1 of the solenoid to a Pressure only source via a tee piece
Port 2 of the solenoid to the top port of the wastegate
Port 3 of solenoid vent to atmosphere
Join the wires from both solenoids together (polarity not important) and then connect them to the brown and grey wires of the
wiring loom
