Does Anyone See An Issue With Splicing Ign 1 & 2 at Harness?

Good morning,

I have been battling issues with getting my MSD 6 AL back up. I bought a new box and was running fine for about 4 days. Yesterday, I was driving and felt a skip for a second. It happened twice, and I shrugged it off as maybe a carburetor blip. I got on the Interstate and before the 1st exit she died. It will crank and combust for like 2 seconds, or as long as you keep the key cranking. I called MSD support and the short term fix is to direct wire the small red to the battery, and cut off engine by disconnecting that wire.

Somewhere, in the engine bay, the Ignition 1 and Ignition 2 wires are not retaining continuity. I redid the solder butt connection (Ign 1/2 and thin red MSD) and still had the issue.

My thinking is that to avoid all, should I try splicing the Brown and Blue wires (Ign 1 and 2) right at the harness under the dash?
I know certain wiring makes the coil charge all the time and I don't want to cause issues with the alternator. But, not sure if this will do either of these things.
