Default Coil relay?

I have a 13b swaped into a b2000, I'm going to use 4 trailing coils for ignition.
what size relay amperage would be needed? and what size wire should I use to from the ignitor to the coil? ignitor mounted inside passenger firewall, coils mounted on top of the block. wire lenght would be approx 3' - 3.5'

30 amp relay and 20 amp fuse will be plenty.
