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
