The fuse panel wire harness route path shown here - cable-tied to the inner side of left frame rail and portions of the stock OEM harness that runs along that same frame rail - did not create any problems with clearance or pinching by the underside of the stock OEM seat pan.
The fuse panel wire harness continues along the left frame rail to a point just forward of the frame rail cross-member near top rear of gas tank. It then splits right-left as described below.
The continuing Wire Run “A” is the fuse panel’s main positive & negative leads to the battery terminals . . . and to the stock OEM Fuse Panel’s positive “Accessory” terminal. That third wire connected to the OEM fuse panel Accessory terminal is the wire that provides power to the FZ-1 relay which powers any of the circuits for which the fuse insertion position makes a circuit “switched only”, powered only when the ignition key is in the “On” or “Acc” position.
Wire Run “B” continues across the bike from left side to right side, over the top of gas tank and in front of the Relay Bank Housing Box. These wires are the positive and negative power wires for connection to your add-on electrical accessories. I utilized 14 gauge stranded wire, double wires similar to “lamp cord”, colored red and black, obtained from Radio Shack, for easy visual ID of positive and negative wires for each one of the circuits attached to the FZ-1 fuse panel which exit from the trunk body. The power connections to existing accessories were made in the region under the right body side cover where there’s plenty of room for routing, connecting and tucking wires above, below and behind the gas tank body. The ends of the remaining two (presently-unused accessory-item circuit wires) were shrink-tubed and tape-wrapped for protection against short-circuits and the weather. They were cable-tie-routed along the lower frame side-rail beneath the gas tank, above the passenger footrest area, beneath the right body side cover, where they are easily accessible for connection to additional accessories in the future.
With the exception of the direct-connect screw terminals on the FZ-1 fuse panel, stock OEM fuse panel and battery terminals, any-all wire connections were soldered, shrink-tubed and tape-wrapped for reliable and weatherproof connections.
COMMON GROUND & “HOT” BLOCK
Had occasion to desire a common ground block. In the past I’ve used the common ground block offered by Electrical Connections Co. on prior GW and was perfectly satisfied with it, but wanted to go a less-expensive route this time around.
