hey guys where did you tap for power for a wideband install?

 

I tapped my 12v accessory port plug wire. I rarely use it and it is switched with the ignition.

One idea if you use your 12v accessory plug, is to run a fused line from the battery to the relay and use the power plug to trip the relay. Itll use less power through the plug and you could still use the plug to run stuff while using the wideband.

 

thank you

 

If the tap is 'hot' while the key is in ACC do NOT use it. You are not supposed to power wideband sensors when the engine is off. I believe the power tap is hot when the key is in the ACC position which could lead to burning up the element, but I may be wrong. If you power the sensor when the engine isn't running the heater element will heat up, but there will be no exhaust gasses going across the sensor, which helps the heater maintain its temperature.

I tapped the main ignition wire going to the key switch with a 3A fuse.

 

any pics of install??
