Hi royal50 . . .

If you are using the original light switch there are separate terminals for the Head Lamps ("To Dimmer Switch" like big bill II points out) and for the Instrument Lights:
49-53 Chevy Service Manual - Chapter 12 Page 42

the index to the whole manual is:

A harness with a fuse panel is more complicated at first glance because everything has to go through the panel before going out to what is actually being powered.

Like Beater says spend some time studying before doing any wiring and you'll be ahead of the game. If you can find someone who has "been there done that" it would be helpful - but you learn more by taking your time and doing it yourself - or you learn just enough to ask some well thought out questions to the manufacturers tech line . . .
