Here's instructions from a NOS Signal Stat 900 I have for my GMC.

The 7 wire switch gives you more options now or in the future.
I'd go ahead and wire it in as instructed, even if you don't connect lights to the ends of everything.
If you ever have a trailer it'll be extra handy to have that already done, Or if you want more or different turn signals.
