I ordered a new turn signal for my 1949 chevy 5 window 1/2 ton truck i also rebuilt the turn signals with new wires and rubber grommits i am presently running new wires for certain circuits anyway heres my question

if i wire the turn signals switch up the way it tells me to in the schematic how will i have parking tail and brake lights there are a lot of wires just hanging under the dash heres the best site for wiring diagrams for reference if need be
