Hard to say. Could be turn signal and hazard flashers, and factory alarm horn. Can't make out the fourth one.

What year is your car? The first photo is of the turn signal flasher module. The 4-way flasher module is on the fuse block. Not sure about the others due to differences between model years.

I could tell you on a 68, not sure about 77. But the round one on mine under the console is hazard flashers, and one of the square ones was part of the wiper system.

If you go through all the steps for buying one, the OSoEZ wiring diagram from DrRebuild would tell you. I would call to order, it's easier than filling out the form on line.
