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.
