Wiring the Fuse Junction Box

[62lwbc10]

Hello All I just finished rewiring my 58 with all original harnesses and it seems I need to add an original style fuse junction box because I want to run the Deluxe heater and some other accessories. The shop manual for the deluxe heater install shows the wiring going to the junction box. ANy of you have this junction box? Can you please tell me how the junction bix itself is wired up to the ignition switch and/or the headlight switch? Thanks
