same prob on how to wire it? 4 wire right to the o2

 

I believe it's no big deal if you switch the black ones, although I'm not sure if they go to a power distribution terminal or the common ground terminal. I don't have my diagrams on me but if I remember to I'll check this weekend.

 

thanks

 

yes it does matter, i once wired mine wrong, and couldn't for the life of me figure out what it was, the check engine light would always come one. I switched the black wires, and everything was fine.

 

Hmm, well there you go. I didn't have that problem but then again I was careful when I messed with my harness and made my O2 extension to keep track of the right wires so they didn't get mixed up...always a good idea to label them before cutting...

 

well my check engine light isnt on anymore so i guess i got it right.

 

Well, in any case you have at least a 50/50 chance since there's only 2 wires, right?

 

ya there's only two black wires that can get mixed up but it seems weird that both times i rewired it i got it right.

It's like playing the lotto, the odds don't change regardless of how many or few times you do it.
