Controlling an automotive electric throttle body

Hello, i have a project where i'd like to control airflow with the use of an automotive throttle body. I'd like to set it up so that i can have the throttle go to a specific percentage of open (0-100%) based on inputs. My question is trying to figure out what kind of signal to send the throttlebody.

Here is a link to a pinout for it.

Pin 1 Throttle Position Signal #1
Pin 2 Sensor Low Voltage
Pin 3 Throttle Position Sensor 5 V reference
Pin 4 Throttle Position Signal #2
Pin 5 Throttle Position Actuator Control Close
Pin 6 Throttle Position Actuator Control Open
Pin 7 Throttle Position Sensor Low Reference
Pin 8 5 Volt Reference

The Pin 5 and 6 kind of throw me for a loop, do you just send positive voltage to 5 or 6 depending on if you want it to close or open?

Thanks,
Grant

Can't tell without more information - a photo of the unit might be more informative. Have you measured the resistance of these control signals to ground (they might be separate motor windings for instance).
