The photo is an auxiliary fuse Panal, instead of wiring accessories form the bikes wiring harness the fuse panal is attached to the +/- on the battery, the fuse panal is then live and fused to take any accessorie up to 60 amps.
Let me know if you forsee any problems with this idea, me and Les have talked about it before, the price $49 00. here is a photo of a different panal.
