Default Heated O2's

So got everything wired up, all the pinks to key hot and orange to battery hot. But I noticed while under the car and keys out of the ignition my O2's are heating up. Is this the pcm's doing? Did I some how give a certain pink wire a consistant hot fead thats allowing this?

Is this normal? lol


I would think this would drain the battery if its always heating up?

Your help as usual is appreciated!

Should be no power to O2 heaters unless ignition is in run position.

Lol I was thinking well maybe the computer was learning new perameters after the new flash..lol

I knew all my pinks and oranges were wired correctly so I was thinking that it was a deeper problem or wiring ahead of the computer...easy fix!

But stay tuned there will be plenty more wtf's!!

thanks
