According to the instruction book, which is not always correct !!
Starting at the bottom
1 Brakes horn, headlight flasher, pto light switch
2 Indicators
3 Hand light socket ( ??) Instruments, indicator lights
4 RH Front and rear parking lights, dash panel, rear work lights
5 LH front and rear parking lights
6 RH Dipped light in the radiator or in the cab roof
7 LH as above
8 Main beam lights and indicator light
9 screen wash, both wipers and heater fan relays
10 Heater fan and ceiling lamp
11 feed to fans
12 rear work lights ( cab roof mounted)
1-8 are in the main box,9 10 11 12 are in the small one
according to the book they are all 15 amp, but we find that larger ones are necessary for heater fan and headlights
Hope this helps, Dave
