Ignition switch rod won't stay in on '78 K10

[cudajim]

Last night I checked for lit bulbs (or not). Found the heater control had no light, replaced burned out bulb this morning. Also found there's no backup lights. Found bad/intermittent/flaky switch down low on the steering shaft. Same switch assy. as neutral safety switch which was working. When I jump Lt GN and Dk GN wires together I get rear backup lights. Anyhow, I'll replace the switch this afternoon.

Jim we did everything with on our cluster from LMC. Turned out great. With your background looks like it will be way easy!

Welcome and thanks for sharing your experience for those of us who struggle greatly!!

Very nice pictures (above). I do have one last question. There is a light bulb hanging down from behind the instrument panel, it has 2 wires attached and is about a foot long. It never lights up and I don't know what it plugs into. Anybody out there know?
