Hey everyone. After a few long years of being in storage I've finally started working on our 72 Barracuda. Mainly mechanical stuff, but I'm trying to clean up some messy wiring, etc, from the previous owner. When working under the dash I noticed there appears to be a cable/knob that is missing from right under the dash to the left of the steering wheel that looks similar to the knobs used for opening the air vents. Any idea what this is, I have it circled in red? The knob is missing, it looks like someone yanked on it and broke the end off. Just trying to figure out what I'm missing so it can be replaced.
