Converting from Crane Fireball to 123 with blue coil

[jmr_1602]

There is a ton of info on ignition wiring on the FAQ and I am second guessing myself. So, I just want to confirm my understanding.

 

First here is my current set up.
- 1970 6 fuse car.
- Crane Fireball with a ballast resistor.
- Starter Relay

 

I will be switching to a 123 Bluetooth distributor with a blue coil. I know I don’t need the ballast resistor with the blue coil, and I want to get rid of the starter relay while I am at it.

From what I understand, I need to run my green ignition wire to the positive post on the coil and the tachometer wire to the negative post.

 

For the starter relay I can toss it all out and remove the red and black wires from the starter.

So, is my logic correct? I’ve read that the starter relay isn’t needed. Thanks for any help!

Any insight?

You have it right. Red wire from the 123 to the coil positive, black wire to the coil negative with the existing black wire that goes to the tacho and old connector at the condenser on the distributor. Tape this  distributor connector up and stash in the wiring bundle along the firewall. Blue wire to ground (this can be under the coil bracket screw).

Thank you Simeon! Even after studying, I never scored well on tests. I just needed some verification.
