probably, but an output circuit would have to be built to run it.

What would the circuit need?

EDIT: quick search found this

The VICS actuator should have vacuum at idle and changes state at 5000 RPM. We have used ALED as the output to control the VICS system at Connectorboard 4Q with RPM as a single output condition, a threshold of > 5000, a hysterisys of 300, "power on" set to 0, and "trigger value" set to 1. This all means that the output will activate at 5000 RPMs, won't turn back off until 4700 RPMs, is off when the MS is powred and the engine is started, and is activated when triggered

I might be late to the

but I was searching through pics from my build thread and this is the best pic I have of the inner side of the mani. That's the check valve right there i think?

Hope it helps?

I know this is an old thread but I am working on installing the VICS but using race capture to run it instead of a RPM switch or megasquirt (still using factory 1.6 ecu). We have the script in the RCP correct and the wiring to the relay correct, However I dont think we wired the solenoid correctly. Can you guys tell me what the pinout of the solenoid is? I followed this thread to get the vacuum properly hooked up. Now just checking the wiring.
