Relay terminals

Got a relay, 30 amp. (no hang up tab was available). There are 4 terminals.
Correct me if I am wrong:

1:Terminals #85 and #86 are the coil terminals and polarity is not an issue?
Should I put a smaller fuse in the battery side lead to the coil?
2: Terminal #30 is the power in tab (battery side) and must be fuse linked
with say 25 amp fuselink.
3: Terminal 87 (which is turned 90 degrees from the other 3) is the power out
to the fan.
10 gauge wire on the high amp side. And is 14 gauge ok on the low amp side as I have some available. I plan to place the relay in the engine compartment as close as possible to the fan, so as to shorten the high amp wire length. Then will run the low amp switch wires from the dash. All will be routed away from the exhaust areas (no problem)

Am ready to fly upon your approval or correction of the above.
Yes I am compulsive, but it pays. rap
