I need to find a keyed hotwire for my heated O2 sensor.....I tried the temp gauge wire but it cause my gauge to peg out...then I tried the oil pressure wire and it also causes my oil pressure to peg out and not work....I know I have the O2 wired right...I just need to find a keyed hotwire to power it....which one do you guys use that will not cause any kind of problems like what Ive been having...I thought maybe it was the O2 so I went and got a new one..

what wire?

what will happen if I dont have it heated?

Take a test lite and go to your fuse panel.
Might have a keyed fuse slot open. If open fuse it and use it.
If not, take it off one of the higher amp fused components
that are keyed
Good idea to run heated when running headers.
