It is recommended to ease configuration that cam position control solenoids are wired to the same number Auxiliary Output channel as the corresponding cam position Digital Input (refer following example).

Although not absolutely necessary, it is recommended to ease configuration that cam position signals are wired to the same number Digital Input channel as the corresponding solenoid control Auxiliary Output (refer following table).

For compatibility, the following use of Digital Inputs and Auxiliary outputs is recommended for VVT wiring. Note that in practice any Digital Input/Auxiliary Output combination can be used.

Solenoids MUST be wired directly to an auxiliary output channel DO NOT wire continuously variable valve timing solenoids through a relay as high frequency switching is used.

Some factory systems use 12V switching to control VVT solenoids. These solenoids must be rewired to be ground switching.
