I am putting narrow-band back into my car to help tune cruise idle etc. I am digging out the wires, and it appears that the o2 receiver plug has a thick red wire, 2 black and 1 white wire. Where do each of these go?

The pair of black and white are shielded. where does the other black go? Ugh I should have never cut this friggin connector off!

car is a 1992.

Pics included would be boss.
