Electrical Upgrade - Items to consider

Hope everyone is doing great. I am doing a few electrical upgrades on my car and wanted to get some suggestions... and of course do it right the first time.

What is new:

- 215 amp Powermaster alternator with internal regulator (8-58539)
- Upgraded charge wire coming off the alternator (2 AWG) and to the "battery"
- New wiring harness

For context, I have previously done the ampmeter delete and replaced it with a volt meter.

I plan to "bypass" the bulkhead with new harness and be done with that.

My question is with regards to the "splice" there the black and red wires meet behind the gauge cluster. I am thinking of using a connection like this to connect the 2 wires together and to run my accessories (4 ways, cig lighter) and key on power items (radio etc) to.

Good idea?

Also, what size "fusible link" would be recommended for my alternator? Can you recommend something?

Any information/tip would be appreciated

Thanks in advance
