Hello,
I am installing a Boss Audio MCBK420B https://bossaudio.com/powersports/mcbk420b/
I want to wire the power into one of the ignition wires that is hot when the key is in ACC...
Here is where i am..
I found a brown and white wire that comes off the back of the ignition, it is hot when the key is in ACC position.
I found a "not in use" aux plug that is only hot when the key is in the ON position....just like the cigarette lighter plug right next to it.
Can I splice the red power wire from the Boss into the brown/white ignition wire and the black ground into the BUS? My last pic with the question marks is the BUS i believe...but i don't exactly know what the BUS is..
