E90 328 Throttle Pedal Wiring Diagram ?

Does anyone have the wiring diagram for the foot throttle pedal?

It is 6 pin/wires. And when looking at the car side plug, numbered as-
1 2 3
4 5 6

pin 1- brown with yellow stripe
pin 2- brown
pin 3- yellow with green stripe
pin 4- white
pin 5- yellow
pin 6- white

So something should be- ground, 5v reference, signal (0-5v), IDK what else.

Any help? Thanks

My idea is to tap and monitor the 0-5v signal wire and I will then map out the throttle position voltage. I can use this voltage to turn on a switch/relay.

For example if half throttle is 2.5v, I can monitor the signal wire and when it goes above 2.5v, it turns on a relay, which would turn off when the signal voltage drops below 2.5v.
Or turn on Nitrous when pedal is beyond 80% position. Open an exhaust dump valve when above 50% throttle position. Open electric BOV when throttle position is below 15% and above 5%. The possibilities are endless.

I want to be able to turn on and off some things depending on throttle pedal position.
