Bosch 75A Relay with switch, wiring q

[281pony]

i picked up my 75a relay from the parts store today, it came with no wiring instructions. he photo copied the back of another 5-pin relay for me (bosch is 4), and told me to use the numbers on it for reference. i did a search when i came home, and found the suggestions on here to be different for the most part. the photocopy i have, suggests i use this wiring method;

pin 30- + fan wire.
pin 85- ground wire off battery
pin 86- + switch wire
pin 87- + 12v off battery

then a seperate 12v battery power wire to the switch.
is this the correct method? im using a 50a switch, 2 prong.

how exactly does this get wired in if the info on this copy is not correct?

The rating on the switch doesn't matter anymore (it will pass less than one amp now that you have the relay).

I would reverse 87 and 30. Be sure to fuse that battery power to the relay.

ok. i sent you a pm regarding just wiring in a fan controller while im attempting to do this.

what size fuse is correct for the power wire? 30 amp?

PMing. Need to know if you have AC.

Reverse 30 and 87.
