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.
1. 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.
2. If your bike lacks a fuse box, you can connect the yellow cable to the tail light wiring harness instead. To access the tail light wiring, remove the seat and rear fender panels to expose the area around the tail light. Next, remove the tail light housing cover. Use a multimeter to test the wires and identify the one with power running to the tail light—this is the wire to connect the yellow cable to.
How to Connect the Yellow Cable Without a Fuse Box?
So keep it simple - red to battery positive, black to battery negative, and yellow to the ACC line or tail light wiring harness. Follow those wiring basics and you'll be powering up your new accessories like a pro!
