Default Pulsed output

Hi.
I'm all out of 0-5v analog inputs on my ecu.
I have frequency ins I can use.
What exactly is coming from the white wire on the green harness and whats the best way to use it for logging.
Thanks

I scrapped my Exhaust manifold back pressure sensor and used the 0-5v analogue for the hfs3 logging.

white wire is the raw signal of the flow sensor. The pulse frequency is directly related to the fluid flow. You need to create a high/low table on your ecu to catch the status, flow vs load.
