Wiring for a engine stand

So I think I have this correct so far but for the fan where would the fuse go and the rest of the wires for that and would you put any more fuses anywhere?
Also forgot at the ballast resistor for the brown wire where does that go to ?

You want 30 for the starter relay hooked direct to battery and not through power switch

Wire fan relay same as starter one, that is 30 direct to battery and a fuse/ breaker in the 30 line if desired (good idea)
Ground the coil 85
Run starter switch/ fan switch of the BATTERY not the ign switch. This is so you can bump engine with igntiion off and so you can run the fans for cool down after engine shut off
