i think you tap the black wiring from the 16-wire connector from the ECU....

 

does the power wire go there (to ecu) or does the sensor wire?

 

the wire to the sensor goes to the black wire on the ECU. You can take your 12V right on the ECU or on the fuse relay thing under the dash if you look under, right above the pedals. Any 12V standard is good. Even the one from the radio or anything else.
