Spotlight install

[Lib88888]

Anyone know where I can pull the wiring through from the engine to the drivers cabin? Is there a side that’s easier? Just need to pull the wiring through to install a switch for the spotlights(new to this) thank you

Through the main wiring harness gromet below the brake booster.
I taped the wire to a knitting needle to feed it through.

Hanger wire works too.
