I just got an original clock for my dash since the car didn't originally have one installed. There are wires behind the dash for the clock, however the clock itself appears to have had the original wire cut from it. Can anyone direct me in the right direction for what type of wire and plug(?) I would need to install it.
I'm a total newbie to all of this, I've only had this beauty for less than a month...
Thanks for all your advice!!!

 

The clock lamp will be a gray wire and I THINK there may just be a wire/harness that you have to plug the clock lamp pigtail into.

Power feed should be a red or orange wire, maybe with a black stripe. Again, maybe just a wire with a female plug on the end that plugs onto a male terminal on clock body.

The ground wire on 63-64 full-size car clock runs from the clock body to one of the mounting screws. Not sure on Cutlass but should be similar.

Strongly recommend purchase of a 1963 factory Chassis Service Manual if you don't already have it. Look for a late printing that has the update pages pasted in.
