I've read the write ups and have successfully used the EGR input as a wideband AFR input for the stock ECU (for logging purposes) with HPTuners using pin 55 on the Blue connector

I have also used the Air Conditioning input on other cars. On say 99-02 camaros, pin 14 on the red connector is for the AC pressure sensor. They use a 0-5 volt sensor rather than the low/high switches like the trucks do.

I was wondering if I could use pin 14 on the red on my truck and still be able to see the incoming voltage on that pin to be able to log another sensor since I am already using the EGR and fuel tank pressure inputs for my dual widebands. If I can use the 14R pin, what parameter would I log (since typically this pin is not used).

Thanks! I hope someone else has tried this!
