I have just finished doing this mod on mine, Only I have put the relays above the fuse box so there's less wire for the power to travel down (and harder for
to find) & wired my kill switch back in.
Now when I stand on the brakes the dash lights don't dim.

I have had 'interesting' (to say the least) experiences when trying to cut multiple neutrals with 1 switch. It tends to back feed & switch a relay (or 2) on & uses the others as a earth. I initially tried wiring the headlights & fog lights in this arrangement. Then when I turned the key off, the headlights would go off like I intended, but the fog lights would then come on!

What I'll add to this now is that around a month or so I suffered a repeat of the failure to crank, solved by a short length of wire direct to the start solenoid trigger terminal. It turned out that the contacts in the (cheap
) relays I had used had become high resistance with only a short period of use. Nowhere near their rated current capacity either.

i always use old rellays from off cars.. toyota relays are really good and though say 40 amp, will survive a constant 80 amps.. with a little voltage drop.. but always make a good connection.
i did this on my panda for the lighting ring. then i just added every other relay to that haha. now i have a 150 amp switched and fused "ignition live". for running my other car's spot lights and ham radio gear.
