Question for you wrench heads. In this case, it is an electrical question. I'm installing a fairing on my bike. I'm installing the Kenwood KMR-440U. My question is regarding the power. There are two positives. I understand that the red wire is when you turn the power on, the stereo turns on. I'm installing a relay. I'm following the diagram below. My confusion is the yellow wire. I think this is the trickle power to maintain the memory presets. How should I wire this?
- Should I wire this directly to the battery?
- Should I wire this directly to the battery, but put a fuse in between?
- Should I not install the wire at all?
- What other options do I have?
Any advice is greatly appreciated. Thanks.
