This is what I have instead of fusable link and powering my electric cooling, and then blade fuses and relays from there on,
I have 4 relays for headlights (one for each bulb element) so I will never loose both lights if I loose a relay.
They are also soldered direct and not using a pigtail socket.
I still use pigtail sockets right at the bulbs though, but with much larger wires.
Also, like Del mentioned I grab my relays out of Honda cars.
Pisses people at Walmart off, but...):D
Just kidding.
I have a stash of extras from the pick a part.
