8-10 awg wire connectors

On a side note, you really should be considering adding at least two relays, maybe four

One for the key to activate for the ignition loads and VR system, other underhood stuff
One for the accessory line
Two for headlights, one for high, one for low beam

I have relays for the headlights and the fuel pump now. Thought about the ignition switch and accessories. Thanks for the reminder.
