Wiring up 3 wire o2
I have a heated oxygen sensor on my car and was wondering where would be a good spot to put the power wire for the heater to. I had it wired in with the fuel pump but the fuse for the fuel pump always blows when I turn the key on. What else would be a good circuit to wire it in with?

Re: Wiring up 3 wire o2
I used the line that goes from the relay to the pump (it is energized if the engine is running or when the key is first turned) to trigger another relay that powers the O2 from the battery. It hasn't blown a fuse yet.
Hope this helps.
