Well installed map sensor , to the erg pins ...I also had my wideband hooked up to the erg pin at the ecu ...Went to swap the brown wide band wire to pin 4 (white)-( oxygen sensor input) ...But i followed the white wire out of the car and its connected to the cas ..Only thing left would be pin 16 correct ? if so am i just splicing onto it or cutting it then wire the brown wire to it...
