ok i have a AEM wideband and i have to connect it to a costant 12 volt source, reason why is i get too much feedback through my stereo, so i have it connected directly to the battery, but it stay on all the time, so could i connect a relay to the power wire and wire it up somehow so that when i turn off the car the wideband turns off even though it recives power all the time, also but when the car is running it works as normal could some one tell me where the wires go and the numbers and stuff, thanks

Simple. 85 ground, 86 ign, 30 Constant from battery (fused), 87 output to wideband sensor. This way it will still recieve power directly from the battery and shouldn't interfere with you radio.
