1963 c10 electrical problems

[nutsfor59]

problem #1 i have no power at ignition switch unluss i run jump wire from battery over to horn relay,i've seen a couple wiring schematics that appear to show this,is this correct ??? or is there another wire thats supposed to share the pos post on battery or is that just supposed to just the main cable to the starter ???,

problem #2 when i pull the light switch out i get headlights but no dash lights,there is no power going through the instrument fuse on the panel unless i bring a hot feed to the terminal on the side of the fuse block at that point,what is correct ?? is there a wire missing ???,i've been using a test light,new switch etc.......electric no my strong suit HELP !!!!!!!1

THANKS

A 10GA or so wire runs form battery to horn relay, truck feeds from the horn relay. Headlight switch likely bad causing dash light failure.
