One more  for this thread... what size of fuse are you guys putting between the alternator stud and the relays?
Thanks,
Darren
I have a 15a low beam and 20a high beam fuse. Depends on what bulbs you are running. Mine are aftermarket H4's.
If you take the resistance of the low beam filament, then divide 14 (avg voltage while running) by your resistance reading, then multiply it times to (bulbs). You will get the amperage draw for the low beams. I'd go up to the next size to account for any surge. And do the same for the high beam. (high beam filament will be lower resistance than the low beam).
Example
Bulb resistance 1.5ohms (just a random figure)
Avg running voltage 14v
14v divided by 1.5ohms = 9.3a x 2 bulbs = 18.6a (i'd run a 20a fuse)
