pretty sure you need to hook a clock to the same wire that powers the lighter
I know the 68's and 9's were that way
it is also the same wire (orange) that supplies power to the courtesy lamps and should also be listed on the fuse panel
this one will stay live when the key is off

Back in those days everything was an option. The clock was one option. The way it tacked into the main harness was an option harness. M & H will sell you one. Look under 70 Chevelle.

you can buy a harness (but is really just a waste of money and isn't exactly stock anyway)
a soldered splice to cigareete lighter circuit is all the factory did for this option

You can connect it as Tom stated but you will need to run a ground wire, as the sweep speedo cluster is plastic.

If correct is a concern. The clock on a 70 sweep dash, from the factory or by the dealer, used a separate harness that connects to the BAT terminal on the fuse block for power and at the parking brake for ground. The SS or optional gauge dash has the clock power connection built into the harness.
