My ideas:
Hook that seat belt light to the reverse lights for an idiot light in your face.
No one still has that warning and start prevention hooked up do they? I call that the imposed Nixon circuit. That bastard even screwed up Mopar wiring! I think the interiors seat and carpet quality got crappy at the same time they imposed the seat and belt wiring.
I have a switch for the engine compartment lights in that hole now. The fader knob hole, has a switch for the tach and the floor shifter lights. So they can be switched when the parking lights are off. And (might as well say) the blank spot on the headlight panel has the electric fuel pump switch.
Next, I'll hook my reverse light to the old, line lock red light next to the e- brake release. For an idiot light that can't be ignored.
