Replaced factory stereo: Need accessory switched power

[Steven Douglass]

Hello fellow jetboaters!

Yesterday I carefully removed (and kept) the factory JBL stereo, replacing it with a nice Pioneer media tuner. The factory stereo wiring acc (red) and constant (yellow) wires are hot all the time so the media tuner does not power down as you'd expect when it's "off", so this will inevitably lead to unwanted battery drainage if I leave it as-is.

In a perfect world I'd tie into one of the main engine switches so when the key is in the "On" position I'd get switched power and when I shut down for the day and take the key out the stereo powers off properly (like in a car). However, I think a main engine switch in the "on" position will cause unwanted battery drain with the ignition circuits being powered. Plus if this was a good idea I suspect Yamaha would have tied the factory stereo into it, which it seems they did not.

Any recommendations on where I can tie in to switched power?

As a fallback I can install a hidden toggle switch under the dash for switched stereo power but I'd like to avoid doing this if I can.

Thanks all.

Decided to go with removing the face of the stereo to power it down at the end of the day. No new switches added.

yellow with red stripe coming from the back of the ignition switch?
