Has anyone got a wiring diagram for the Bosch throttle potentiometer as fitted to the Boxster and other models? (Bosch part no : 0 280 752 010)
It appears to be near identical to the one used in the '98 Diesel Freelander and the 98-06 Lupo too, so they may help if the Porsche info isn't available

6 wires out:
brown
grey
yellow
white
green
pink

I'm expecting one pair will be a 0 to +5v and another pair a 0 to -5v with the final pair a power or similar

It's not going back in a car, I'm working on a little Drive-by-wire project (and yes I'm well aware of safety issues and whatnot, this is just to help me get a test rig set up), and am trying to work with the bits I have at my disposal

If anyone can go a step further and identify any specific signals that are sent, then that'd save me hooking up a scope and reverse engineering it smile

Looks like its just a dual pot - Green/Grey with Yellow wiper - pot1, Pink/Brown with White wiper - pot2.
There's a diagram at Pelican Parts under tech articles / boxster
