Mystery lamp ?

My cuda has a key switch light, I changed the ignition switch the other day and had it out...pretty sure it was a orange wire.
Look above your key and see if there is a hole for the light to glow through..
I can take a picture of mine if you want.
Ignition switch keyhole light is yellow w black stripe. I have redone 2 AO1 light package harnesses. One of which I added to a 67 barracuda which was never offered including the time delay relay and keyhole switch light (had to drill hole for lamp). AO1 includes brown and yellow wires for the map light, yellow with black striped that go from both double spade door switches to the time delay relay and into the keyhole light to trigger the relay when either door is opened. A pink that goes into the glovebox lamp. An additional orange that clips into the ashtray mount housing.
