Hey guys I found a wiring diagram for the Corona but it only shows the power coming from the ignition and nothing else. I can figure out the wiring for the speakers but where did you get the constant power for the clock on the radio and presets and are you just grounding off the chassis.

why not run it off the cigarette lighter line , isn't that a constant positive line in oldschool cars ?

Here is a corolla wiring diagram, maybe you can trace it

My Corolla was similiar. Ran a wire to my battery for constant. Power of an accessory wire (just used a cheap current tester on my fuse block) and then ran new wires to new speakers.
