[Livingstonm]

Hi guys I'm new to forum I have a 1970 Chevy c10 that has been converted to 4wd and lifted.. anyways I about to rewire the truck the kit is currently shipping my question is that there is 2 black fused wires on the diagram that don't seem to go anywhere in the cab.. do I need these wires and if so what fuses any help Is appreciated

They go to the factory ammeter in the gauge cluster. One wire comes from the battery, the other from the alternator. Both wires should have a 4 amp fuse. There's been a ton written on them here on the site. A quick search should tell you all you want to know and probably some more!
