whoe...awesome. Thanks, you guys!
So...it's a little more intense than I thought it might be. I was reading this write-up:
http://www.picotech.com/auto/applica...e_control.html
So I was figuring it had a TPS sensor(which I can see molded into the plastic housing of the throttle body) and figured 3 wires went to that, and then since the motor is a servo motor and most servo motors have 3 wires I figured another 3 from that...but that's only 6 wires and this thing has 13.
But now I see...the pedal connects its two position sensors directly to it and the control module figures out its own stuff. And I guess it also has a built-in cruise control hince the speedo signal and the brake light signal? Or maybe that's something different and it just behaves differently depending on these signals...IE closes throttle body if you go over the speed limiter, not sure why it would do anything different with the brakes on...you think you could still rev the engine if in neutral with the brakes on.
As for the serial connection...I guess that's something for the CAN interface(controller-area network)? And maybe it reports the built in TPS signal through that? Because I don't see any other lines that go to the PCM for the TPS signal. Maybe it just uses it internally for controlling the throttle plate?
