Need help with 02 faster the better.

[blackSS01]

Long story short. I bought 2 new 02's. Bosch universals, $70 each. Had codes for both sides, front ones, 02 sims in rear. Replaced, and still have 02 Bank 1 code lean. Had to cut off the old harnesses and wire together. (Stock harnesses from car, never touched) Black wire, Grey wire, Two White wires. I wired black to black, grey to grey, and white to white. Problem is there is two whites, could having them hooked wrong cause the code. Help would be super apreciated.

Number for Bosch is 15732. One code is cleared, just one came on so it has to be wiring. Only have 40 miles on them.

Bosch universals....is probably the problem.

Of course, having to cut those VERY sensitive wires doesn't help either.

Dang, why did you get universal o2's?

[blackSS01]

Long story short, I know they are junk now, after research. I will never buy a bosch again and go with AC Delco. Have it re-wired now, hopefully the code clears.
