01 Tacoma EFIE Install
I'm trying to hook up an EFIE in my 01 Prerunner, but can't find the correct wire from the bank1, sensor1 O2 sensor. The sensor itself has 2 wires that plug into a 4 wire connector under the truck.
I would prefer to make the connection inside the truck, and removed the glove box to access the wires to the ECU. I have been unable to locate the correct wire after sveral hrs of probing and comparing voltage according to the instructions. I rried comparing voltages with the booster both off and on, but no joy.
Can anyone tell me the color code of the correct wire?

I prefer to make that connection on the o2 sensor wire before it plugs into the harness. That way when I have to replace the sensor, all those splices I made prior to figuring out the right wire, go away.Wink

I stripped back my EFIE wire several feet and leave the red and black in the cab and send the rest through the grommet behind the fusebox (by the steering wheel).
