350 TBI Firewall 12v Junction to Bulkhead connection wires?

I'm in the process of eliminating a bunch of electrical components that aren't needed in my '88 r30. All of the headlights, Taillights, blower motor, AC etc basically everything that's not vital to the engine running.

Needs some help with these.
On the Firewall there's a junction box with 12v wires going to the Bulkhead connectors. I looked at a bunch of wiring diagrams till my head was about to explode :mad1:

Thanks in advance.

• Red with a fuse able link
• The One I'm holding with a Red and Black wire
• and one more red.
• I believe the larger Red wire hits the Battery.
