Can anyone save me some time and tell me which wire to the throttle bodies carries the tps output voltage?

Thanks

Our wiring appears to be the same as the E55 wiring pinout, pointed out via this post from Scratch77:

Pins 2-3 and 5-6? Correct me if I'm wrong...I think it's from 0v - 4.5v.... just thinking off the top of my head.

Hope this helps to some degree.

Yeah man, that does help! That's the voltage output I'm looking for. I hate to ask this question, because I can't phrase it in any way that doesn't make me sound dumb, but where would I find those pins? On the harness connecting to one of the tb's? Do you know if they can they be accessed without removing the manifold?

Yeah, it's a 2 way harness, so you can tap into/splice into the wires from outside the intake manifold. When you pop off the Mercedes badge cover thing, you'll see a black and a white connector. When you unclip them and look closely (maybe with a flashlight) you'll see numbers by each pin.

That's awesome, thanks so much!
