FZ-1 Fuse Panel Wiring Hookup Schematic From Installation Guide
INSTALL LOCATION ON 2009 HONDA GL1800 GOLD WING - WITH NO CB / CD PLAYER
(Feasible if you do have CB radio only).
FZ-1 Fuse Block reportedly will fit underneath the left battery side cover on a GL 1500, but it will NOT fit under the left side cover on the GL 1800.
I installed mine in the rear trunk’s CB radio / CD changer sub-floor cavity.
