You need to go direct from double red buss to 2.5 bianco - switched by a new added relay. This requires minimal (and reversible) wiring and a $10 relay from AutoZone.

The fuse ratings are European standards from 1966 - make sure you understand what fuses are correct, and not be mislead by your limited experience.
Classic electical mistakes are
1) fuse replacements with too high rating.
2) bulb replacement with too high wattage.

note - there are single inline fuses to service
air conditioner system - 40A fuse near fuse block
horn compressor - 40A fuse near horn compressor
cigar lighter - 40A fuse behind gauge panel, requires panel removal
fog lights - 8A unknown location

except for three missing terminal covers, this is an OEM GT400 2+2 fuse block, Hella high beam and low beam relays, fan fuses, Foredit washer bag, etc.
