Hey Broadfield,
I'm getting noise whenever my AEM wideband is turned on. I moved all my grounds to a spot on the dash support, to the left of the A/C unit. Thankfully this fixed the noise I had when I used the AUX and phone charger at the same time. But I still get a high pitched whine through the speakers when the wideband is turned on. This happens even with the headunit off, and the key in the off position.

All my AEM has for wires are for power, ground, and 2 wires for ECU logging.
I've jumped both the power and negative to the battery, and I still get that whine. I'm so confused.

Have you ever come across a problem like this?

Thanks!
