Default Help identifying electrical connectors

Hello, 1985 4+3 disaster rehab of a car. Under the driver side dash and the majority of the wiring is hacked up for what may have been an old alarm system. There is alot spliced or not connected. Here, the spade connector looks like a ground but I don't know what these other two are. These are on the drivers side hanging under the cluster/column

Cruise control flat plug goes into the square connector with white tab.

Do your Hazard lights or directionals blink because the other looks like a timer plug

Hazards work, I just replaced the flasher for the directionals so they work now that was on the passenger side behind the breadbox.

Since all the other plugs you are showing are Cruise, that might be a Cruise disconnect switch wire on the clutch pedal or possibly on brake pedal

The connector @ your 'index finger' looks to be an early CSS (Clutch Safety Switch) connector. That would be from the switch. Wire colors are?

That makes sense, as the car can be started without the clutch depressed. I'll see if I can find where it plugs in.

The jumper is CSS to the body harness 'jumped'. The first one in your 1st post is from the switch with likely 2 black wires. I fixed post #5.

I was suspecting the Clutch Switch but since he Didn't mention a bypass all that wiring was connected and functioning, OP anytime you have Creative wiring its kind of important to mention. Because all you needed to do is look up and trace 4" to clutch switch
