MSD 6AL Power Cable connection

I'm installing MSD 6AL (6425) in my 1979 911SC. I saw an old thread where someone wired the power cable to one of the 3 fuses located at the back left of the engine compartment. To save running wire to starter or battery. Has anyone else done this and if so which fuse & side did you use? Attached is a picture of my set up so far with the 3 fuses shown by yellow arrow.
Thanks Team!

Those are the fuses for the rear window defogger, etc.
Best practice is to run clean battery, which means the starter.
Also wise to use a section of fusible link down at the starter end of the cable.

Don't do it, current draw is too high for the wire coming from the alternator through your engine harness feeding the rear 3 fuse panel.
