I've done the battery relocation project to the rear using a M3 sedan battery cable. Problem is, the cable is not in the best shape, especially near the (+) terminal. My car keeps shutting off intermittently. Cause is a poor connection/frayed cable near the battery terminal, especially the thinner cable that goes to the fusible link. If this thinner wire is interrupted, your car shuts off. Lights, horn, etc still work, but when you crank, it does not start.
Anyway...

I do not want to buy a new BMW battery cable. Instead, I want to go to Lowe's or H.D. and get ___ amount of feet of cable and then replace the OEM cable with the generic cable.

Questions:
1) What gauge should I use for the main positive cable? I'm referring to the cable that runs through the firewall, passenger side; bellow the passenger seat, and to the battery on the right rear of the car.

2) What gauge is the fusible link cable AND the actual fusible link?
Thank in advance.
