The FZ-1 also has a built in relay that can activate any of the circuits that are switched on by the key.
You choose either constant on or key on by placement of the fuse.
Finding a wire to control this relay can be a bit challenging.
On 2011 and later RT the Spyder doesn't power down the Load Shedding Relay for about 40 minutes so if you use a wire from that circuit your accessory plug will be hot for that long.
If you want to locate the FZ-1 in the front you can use the light power at the gauge pod (Orange/Red)
For back locations you can use the Gray/Green wire at the heated grips.
Both of these wires are fused and the low current draw of the relay doesn't affect their primary operation.
The above info pertains to the RT.
