I am curious about something related to a project that I am working on... what would be the best way to read the throttle position? Ideally from underneath the hood? I know that I can see the throttle percentage through an OBD device, but I'm wondering if there is a 0 to 5V wire, or a pot that provides variable resistance, or some other mechanism that could be tapped into?

 

I presume it is this you need.

 

Bingo. Yes it is. Thank you!
