wideband wiring

For all you guys running a wide band where did you pull your power source from? I taped in behind the cluster but was getting way to much noise on the line and it was giving incorrect readings.

Thanks in advance

I used this sorta thing, and just checked through the fuses in the glove box with the ignition on and off to see which had power with only the key on


I can check tomorrow to see what fuses I'm running my wideband and boost control off of.
Shut up and drive
