I want to add a wide band o2 to my 95 firebird. I am thinking of removing the ecu pin/wire A9 from the deleted egr system and inserting into the d27 connector to log the o2 with a Dataloging program. Will this work, is it possible, or is there an easier way? I don't want to sacrifice my a/c pressure wire. I know pin d27 will log a 0-5v signal I just don't know if swapping the pin /wire is possible.
