420A AEM wideband install

[Inkdlyfe]

So im pretty sure i got this taken care of but i want a straight forward answer cuz i had to look all over to get the full answer so installing a wideband in a 420a not gst do i just cut the white wire signal and put it to the blue wire signal then keep the original o2 sensor hooked up just ducked off but keeping all the wires but the one white one connected to the harness? then wire the wide band to the ecu which is the solid white wire pin 76?

another side note does anyone know if i need the 2 extra plugs that seem to just add to this rats nest of wires ? trying to finish my wire tuck seeing if i can delete these or not

Not sure if the ecu is the same for the 420a in the case of 2g 4g63 yes the pin #is 76 and rear O2 is #75.
Red wire: 12V ignition power source
Black: chasis ground
White: gets wired to into ecu's pin #76 which is white (on 4G63)
Blue wire: unused

Again this is the process from a 4g63 should be the same unless your ecu is different but would wire it in all the same just need to get a pin out for your ecu to verify the exact pin# for front O2.

And not to sure about the 2 plugs but ive heard them referenced to before in previous threads...
