Is there are easy place to tap in to the factory wideband to add a gauge? I have the RPD already, just need the location of where I can find the AFR signal from the factory wideband.

If I'm reading this right you have an RPD, but are looking to add an external AFR gauge as well, correct?

I honestly don't know where an easy place to tap the signal would be, but the post below might help. It at least gives the pinouts at the PCM for the sensor wires, so you may be able to piggyback there.

I found out that tapping into a wideband can screw with resistances and make the signal going to the ECM wrong. Decided to use the RPD for AFR and get an oil pressure sensor installed, thanks!

 

Buy a scan gauge that plugs into ur OBD2 port and select ur O2. Don't be tapping into it and mess things up when u can just get a scan gauge
