I have it in my car; using the Blaster one- 8207.

123 and MSD work fine together you just have to wire properly. They do a poor job of spelling it out, so we all go through what you are going through to get answers.

I’m going off of my memory right now, so verify before you hook anything up, but if I recall you use the trigger wire straight from the MSD or other CDI ignition to the 123 NOT a wire from the coil like on conventional ignition.
