[HELP]AFR gauge install
Hello guys, I'm currently doing a AFR gauge install, I got the gauge lighted up but the problem me and my friend ran into is we cant find the 0-1v output signal wire. Since all 4 slots on my downpipe have factory O2 sensors connected to it, I am trying to use the green wire on the diagram below so that the wideband O2 can supply my vehicle with stock O2 readings. If anyone wants to know, I am trying to install the ProSport Wideband AFR gauge.
