Ok I am extending my wires and I bought Bosch sensors and they come with a black, a gray, and 2 white wires, I followed the directions that came with the sensors,(I bought universal so they would be longer) and it says it don,t matter with the heater wires cause of polarity or something.
Is this true?
I cut off the ends of my old O2s and am wiring them in.
I know the universal ones are a little more expensive but it makes it easier.

 

Cmon, I know some of you guys have done this.
Are you gonna leave me here on my own?

 

The heater wires don't matter. Hook one up to Ground and the other to switched 12V.........

 

i cut my wires one at a time to make then longer.
