I didn't make that diagram ¿?¿?¿?¿?, but is pretty much the correct way to make it ( including the alternator source )

LOL

however is pretty much easy to make a relay upgrade by yourself. And you can even make it without cut a single wire and install the relays into the cab, being protected from heat and oil, but just if you have your ammeter wiring upgraded, since you should take the power for relays from amm stud.

On my car I used halogen sealed beams. I hate HIDs, Leds and anything like that. Sure they suck less load than Halogens, But I'm stuck with the old fashion halogen "yellowish" light ( and sealed beams )
