Voltage source for electric choke, 1968 coronet R/T

Old Man · Mar 18, 2017

Hello, new friends! This is my first ever post!
I am installing a new Holley with an electric choke on a 1968 Coronet R/T with a 440. What is the recommended or best source of switched 12 volt power. It does not help much that over the years someone decided to spray paint most of the wiring harness, so tracking wires is really difficult. Nor does it help that some of the components have been changed, like electric fuel pump added, MSD ignition and distributor, different voltage regulator, etc. Help me today, and I'll gladly pay you back tomorrow!

use the 12 volt side of the ballast resistor.

Likewise with 'lewtot'

I was too quick- unhook both wires from ballast,,turn on key and which one is hot? Use that one. NOT cranking, just "on".

Was easy to do, but still not ready to run engine after a long layup. Still waiting for fuel line fittings also. Need to service automatic tranny too. It's always something.

Thanks, friends

Welcome.. 68 Coronet R/Ts are my favorite. Show us some pictures

I love 68 Coronets; amazing lines and they look mean with the tail lights too.
I did the same thing last night with electronic choke; without unhooking anything; switched power, engine not running, the ballast resistor in my car is 12 v on the far passenger side and 3.5 v on the side closer to the center of the firewall.

If for some reason that doesn't seem to work out, I'll hook the electronic choke right through the firewall to the back of the fuse box (to a switched power terminal).
