avoiding using relays??

running a relay does not mean you can run a smaller gauge wire. Headlights for example, if you run a relay, you run your large power wire into the relay and then on to the headlights. Your smaller wire to activate the relay comes from your headlight switch saving the contacts in the switch, reducing the current through that, the dimmer switch, and your bulkhead connector... so, what are you going to do about the switches and bulkhead connector?
