Battery cut off switches, Wiring Options

[CG-914]

I want to instal original Bosch cut off switches, like on the original 914GT. One on the tunnel and one under the windshield driver side.

Does anybody have directions for the wiring?
Do you run from the battery all the way up front and back to the starter?

If you want to have a single cutoff switch but multiple places from which it can be activated, take a look at the Cartek GT cutoff switch. It's a solid-state switch that uses normally-closed, momentary-off switches to activate or reset. I put one on my Spec Boxster, and it's been great.

Pegasus Auto Racing sells them:

Or, if you don't mind ordering from the UK, Demon-Tweaks has them cheaper, including shipping:
https://www.demon-tweeks.com/us/cartek-gt-s...tor-kit-242156/

I ordered mine from Demon-Tweaks, and it took just over a week to arrive, but that was pre-pandemic.

You can also order extra switches from either site.

If you want the look of the old-style cutoff switches, you could modify them internally to act as a momentary-off switch to trigger the cutoff.

Also, the Cartek GT has a positive output lug that cuts off 1/10 sec before the main cutoff. I use it to drive a relay that turns off my ECU before everything else is shut off. You could use it to drive a relay to connect/disconnect the alternator output instead.
