You may want to return it and buy an OEM unit. I've read way too many threads about them not being up to snuff outta the box....whereas I've never read that about stock OEM units.

But on our stock 4-wire O2's, the 2 blacks are for the heater section, the white is the O2 output and the green is the O2 output ground.

yea i dont wanna be a dick, but if you can return it and get a stock one you might want to. i have a bosch 4 wire and it started giving me code 43 about a month and a half after install, and now its completely shot, 8 or 9 months later

 

well i got it free from a friend, who never used it.. i'll just try it till it messes up.. blackeg were your 4 wire colors like mine? can you tell me which wire goes to what??
thanks

 

white = grnd
white = pwr
grey = grnd source
black = signal

did some googling :D

 

so bosch just swaps around blacks and white

I know this thread is old but

White and white are heater wires, from what I understand.

 

it should be on the installation insructions, and i have had no problem with mine and ive had it for a year and a half

 

Mine has been working since April, 1999.

The ones I received did not come with any. I was just correcting him for the future when people read this
