Hi All,

In my EV conversion project I now need to wire the throttle to my EV controller (will be fitted in the Engine bay on top of the DC motor assy). I have a few questions that I am hoping the knowledgeable people on this forum may be able to help with...

For the 2004 Base Boxster what is the output of this TP sensor? There are 5 wires coming out of it. I am hoping that the output is a resistive sensor (and not a Hall Effect transducer) and I can get a 0-5KOhm output...:-)
Where does the cable from the TP sensor go to? It started under the dash and goes upwards. I would like to trace it so I can use the wires on the engine/DME end. I think these wires either go to the DME or straight to the throttle body. More than likely they go to the DME since the throttle body uses a voltage input as it is fly by wire throttle

If I am lucky the output is 0-5KOhm and the wires go towards the trunk from where I could measure to make sure and use the resitive output to drive the EV controller.

Any help would be appreciated! Thanks!
