I have a TPS sensor on my TB, but it is connected to my ECU. I'm concerned about applying a +5v reference voltage to a circuit already powered by the ECU. Both the ECU and Traqmate unit are quite expensive, so frying either or both is undesirable.
Is there any other piece of accel data (i.e. longitudinal g's) I can use to drive an accelerator indicator on my dash overlay (TrackVision)?
Thanks Andre'. Cheers!

It makes sense to identify the variable-voltage signal return wire, verify voltage, range and polarity... and t-tap that single wire to input into the TM analog input (similar to the rpm trigger).
Would that not be the correct technical application for TPS input??
