Hi guys

I’m looking to move a fuzeblock (currently near the battery) to under the seat. Main reason is to clean up the spaghetti of wires. Does anyone know the best way to route the cable and what I’d need to remove to achieve this? Have searched on the forum but haven’t managed to find anything.

Cheers
Nick

The wiring I've added follows the bundle up from the aft edge of the battery, slightly in to tuck behind the frame rail, then aft. In coming aft the bundle needed to be flattened as it came past the aft edge of the tank and all the stuff going on around the seat latch. If I add any more, I'm going to cut a hole in the plastic tray for the wires to come through.

I have a PC-8 and not a Fuzeblock, but I suspect the routing of the wires would be similar. My PC-8 is mounted under my seat. Here are some photos of how I did mine:



The wires from the PC-8 relay are routed behind the large vertical frame member shown in the photo.



They're routed down along the right side of the frame, under the fuel tank. I put the wires inside a split loom for added protection. It's a little hard to make out in the photo, but there's a red arrow pointing to the PC-8 wires. I also ran the wires for a 12 volt outlet through this same route; this outlet wiring was also attached to my PC-8. The wires were placed into a reusable cable tie that was already there for some OEM wiring.



The wires enter the area under the seat after passing under that plastic cover that you see in the lower right hand portion of the photo. You don't need to remove anything or cut any holes in the tray, as there's already an opening in the plastic at that location. It's a good idea to sheath the wires at the point they pass through that opening in the tray, as they do touch the tray. The extra sheathing helps protect them from any abrasions if the tray flexes at all while you're riding. I doubt that it does flex, but everything vibrates on a bike, and I just wanted the extra insurance in case the wires were vibrating against the tray where they passed through. I bought the wire sheathing from McMaster Carr.

As you can see in the photo, the PC-8 is mounted on a small homemade aluminum shelf. The shelf is bolted to the side of the plastic tray. There's already a bolt and a threaded hole in that location; it's one of the bolts that secures the plastic tray to the bike frame. I just unscrewed the bolt and then ran it through a hole in the homemade shelf and back through the plastic tray into the frame. The elevated shelf gives you a little more working room to run wires under the seat, since you can route them under the fuseblock. If you look closely, you can see that I cut a slot in the floor of the shelf so the wires can run under the fuseblock and up through the shelf to be connected. It makes for a neater installation.



This is how the completed installation looks. I believe the Fuzeblock is smaller that the PC-8, so you should have even more room to work with.

Hope this helped. I've had this setup on my bike for about seven years and 80,000 miles, and never had any issues with it.

One caveat: If you have an ES model, I don't think this works. I believe there's an additional component under the seat that would get in the way of doing it in this manner.
