Require a bunch of relays for trunk release, starter kill and linking two ignition wires. I see 12V relays with 30 or 40 amp ratings. Is a 30 amp okay for the applications I require them for, or should I go with the 40 amp relays. Any advantage/disadvantage to using one or the other.

30 amp is fine for almost any application.
