View Full Version : Signal wire for a Bosch wideband O2 sensor


Raptor13x10-03-2008, 05:23 PMI'm finishing up the wiring for my 20v 4age w/megasquirt here, and I had a question. I've got a Bosch wideband O2 sensor w/controller, and I'm trying to figure out which wire is the signal wire that goes to the ECU. I'm not sure if I missed it somewhere in there or what, but here's the data I have on the subject:

Sensor in question:
Amazon.com: Used and New: Bosch 17053 Oxygen Sensor (http://www.amazon.com/exec/obidos/tg/stores/offering/list/-/B000BZG9C2/new)

My cheap-ass wideband controller:
JAW (http://www.14point7.com/JAW/JAW.htm)

Wiring diagrams from a different controller, but using the same sensor:

I appreciate any help. :) karl10-06-2008, 11:15 PMit's whichever of the Vouts you program the output to. should be the two furthest wires from the heatsink on the JAW board..

with mine, i set Vout 1 to wideband output, and Vout 2 to narrowband simulation, and connect them on a SPDT switch with the common line going to the ECU, so i can toggle it to NB02 when i'm not datalogging.
