Ignition switch wiring??

Someone needed help with wiring on his newly acquired kit car. As far as
he knows the donor was a 73 Beetle (US).
He claims the VIN starts 1332-something. That does not correspond to any
VW of that era.

The wires coming from the ignition switch a

a thick red wire
a thin red wire
a black wire
a white wire


He thinks the white one is for headlights and needs to confirm all wires
before hooking it up to the rest of the wiring that has been completely
redone (EZ-wire aftermarket system)

These wire colors don't match a 72-73 up diagram AT ALL for a super
beetle. (Which, I believe, was the only model sold in the US in 73, right?)

What the heck does he have??

I told him since everything else in the vehicle is all messed up or
aftermarket, just figure out what key position energizes what wire and
use them to your liking.
