do you guys use 20/30 or 30/40 relays for wiring fans and such??
thanks!

I only use Bosch or P&B branded relays.
BEWARE of the "Bosch type" relays, even though they are rated at 40A - genuine Bosch relays are "only" rated to 30A.

What are you running that requires over 30A of current?

ive used some of the stock mazda relays too. for me, they are easier and cheaper than the bosches

I just put an amp gauge on my taurus fan, if you plan to use the high setting get something that goes up to 80 amps

low settings will be for relay.
high setting will be on a thermo switch

Yeow, you're going to kill your alternator with amp draws like that!
