Got a 5 connector hella relay (little black square style).
has numbers 87, 87a, 85, 86, 30. on it and I have no idea what they stand for as far as the hookup.
Im trying to wire up a pair of 12 inch eletric fans and any help would be great.
The #30 goes to Battery Positive, #85 goes to ground, #87 goes to the fan, #87a is empty in most cases, #86 goes to the toggle switch. I usually use a fusible link to the battery. In case there is a short it will burn before you fry your system. I just wired up a single pusher fan this weekend using this same set up. The fan works great, I'm still running hot but the fan works great.
be sure to switch the ground side with the switch.
