Cut off switch
 

How do you stock guys do the cutoff switch when battery is still in the front (normal place)?

I don't use it, but Painless makes a remote cuttoff. It's a continuous duty solenoid installed at the battery terminal that is tripped by a 12 volt signal from a remote mounted switch. The wire for the trigger is only 14 gauge so running it to the back is no big deal. I have a trunk battery and mechanical switch but put a 250 amp continuous duty golf cart solenoid where the main power reaches the ignition box. I can kill everything from my seat but I can't turn it back on if it's killed by tech or safety from outside. The Painless is around $100 and my home brew was about $50.

Any layout on that? I like it

It is wired like a ford starter solenoid. The continuous duty solenoid can be triggered with positive or negative switching. There are two small studs and i usually hook a jumper from on stud to constant power and the other stud to switched negative. Hope this helps.

On the Cuda I have a disconnect switch on the negative side of the battery next to me just in case.

Heres a shot of the disconnect switch I installed on Ron Muffetts gen 3 Camaro Stocker .
I modified a Lokar cable operated switch to work under the hood rather than in the rear as the car utilizes just the one battery . the control handle is inside next to the shifter.
Solenoid operated relays are a good idea for killing a alternator but involve maintaining power to the control switch. I would avoid using them in favor of a mechanical switch.

All good ideas but I was thinking of how track personnel would turn it off in an emergency, in back it’s easy but not wanting to run big cables to front. I’ve been thing about the solenoid thing too but didn’t want it egauged while in use.

Not a class car but I am using a high amp relay and E-stop buttons on my steering wheel and on the back of my car.

Just use a on-off switch with a negative or positive wire hooked to the solenoid. It can be a 14 gauge wire, The wire connects to the small studs on the solenoid. Hope this helps.

I wouldn't cut the negative side. If you have a wreck and the wire gets cut and goes to ground the relay won't shut off.
