Sup guys I bought a bosch universal o2 but I didn't have the instructions so I was hoping u guys might be able to shed some light on how to install it, the problem I'm having is the wiring, the bosch has 2 white wires 1 grey and 1 black, and I believe the oem has 2 blacks 1 blue and 1 white, wat I basically want to know is wat wire goes where lol I was hoping somebody had done one lately and might be able to help thanks in advance!

 

i need this info as well!

 

Bump man

 

from what i see

the 2 whites on the bosch r the heaters so connect the 2 whites in any order to the 2 blacks on the oem man

then ur left with one gray and black on the bosch right ??
so the bosch instructions beleive ut or not says that the black one on bosch is the signal wire
and the grey one is the ground ....

so can anyone confirm this
