Easiest Place to Tap Constant 12v, Key-on, and Illumination

[CCS86]

Hi guys,

I have a boost gauge to install on my '25 ST and am looking for the easiest area to tap for constant power, key on power, and illumination (headlight on) power.

Thanks!

Here are constant and ignition on power. You’ll have to probe around for lights power. Harbor Fright has a tester on sale at $2.79 that works fine for this.
