I made the following harness to draw 12 v from the battery for my GPS or for recharging the smartphone. The connector is useful also to connect a battery charge mantainer during periods of long non-use.

The 10 A fuse (a regular ATO/ATC blade fuse) is mounted on two faston connectors. The output is a 180923-0 TE Connectivity 2 way female unsealed faston connector. The fuse blades are 5.3 mm wide, but we neverthless used two 6.3 mm faston female connectors (The connector has been slightly squeezed to obtain a more solid connection). The 180923-0 connector accepts 6.3 mm faston female connectors, with the locking lance.

The eyelet terminals connect directly to the battery, the connector is reachable near the main beam of the motorcycle frame, on the left side.

Once mounted the connector can be reached on the left side, under the tank:

The 12 V supply described above is primarily intended to power the GPS system and to charge a smartphone while riding. I assembled a USB charger harness designed to fit into the side pocket of the tank bag. The total wire length is approximately 120 cm.
