View Full Version : Connecting wideband 0-5v aux signal directly to PCM

Instead of connecting the 0-5V wideband aux signal to the V2, can it be tapped directly to the PCM?

A/C is deleted and have deleted my EGR. Can I tap into one of these wires going to the PCM and then call up the PID for one of these signals to data log??

The wideband is already hooked up to the O2 sensor and reads out on the dash. But the auxilary 0-5V output wire can be used too -and I want to splice it right to the PCM.

Has anyone done this??

Yes, 0-5V wideband signal can be done thru either of EGR position or AC pressure sensors... various people have done this.
