Default GM headlight switch wiring

Hi
I am using a gearhead wire harness and it assumes i have a GM headlamp switch....you should see the schematic for that.

I plan on simply using a series of different lucas toggles to switch the headlamps, park lights and instrument lamps. ( or maybe just one )
One of which will be 2 position. As well i plan on using relays to fire the headlamps in hi and lo beam

Has anyone else wired up this way and skipped a standard GM style headlamp switch?

I really only have these wires at the dash


1) headlamp switch power ( hot lead)
2) front park
3) rear park
4) Instrument lamps
5) Dimmer power

Is it simply matter of using this hot lead at each toggle as I believe that #1 wire is the constant feed/supply and the rest would be the loads.

So lets run this by you guys...
My 2 position toggle will have the headlamp switch power feeding in to common terminal. On this same switch will be the front and rear parks tied to one terminal in position one. Then the dimmer power will be on the second terminal to feed the headlightsand park lights in position 2. This switch will break the headlight and park light circuit.

Do you guys recommend another switch for the instrument lamps or should I just piggyback that one onto the same terminal as the park lamps??

I will then have everything off the one two position toggle. As I said before I will use this to fire relays for the headlamps.

GM has room for the dome light ...I don't have that.
