When adding AIO-5 lite to your bike, you'll be working with three main wires - red, yellow, and black. Here's what you need to know:
The red wire connects to the positive terminal of the battery. The black wire goes to the negative battery terminal.
The yellow wire is where it gets interesting. This is the ACC (accessory) wire that needs to be connected to your accessory for it to operate.
When the yellow ACC wire has power, your device will be on and working. If the yellow wire doesn't have power, the accessory will stay off.
So how does this work? It's all about completing or breaking the circuit.
When the yellow ACC wire is powered, it acts like a closed switch. Current can flow from the battery positive terminal through the red, yellow, and black wires, and back to the battery negative. This complete circuit powers your accessory.
When the yellow ACC wire isn't powered, it's an open switch that breaks the circuit. No current flows, so your accessory stays off.
The key advantage of wiring accessories to the ACC line is that it only provides power with the bike's ignition switched on. This prevents accessories from draining your battery when parked.
To locate the ACC wire, start by finding the fuse box. Set a multimeter to DC voltage, connect the black lead to battery negative, and use the red probe to find a wire that shows voltage when the ignition is on but not when it's off. That's your ACC wire to tap into.
So keep it simple - red to battery positive, black to battery negative, and yellow to the ACC line. Follow those wiring basics and you'll be powering up your new accessories like a pro!
