Getting close to the end of a build....what is the kill switch of choice. will be mounted on the battery side of the engine cover extension grill. Thanks, Mark

Moroso, metal construction, better than the plastic units.

I have a plastic one with removable key on the outside, the metal one mentioned above on the inside. The removable key is a little piece of mind during transport or storage.

Btw some clubs like the kill switch to be within reach or close proximity to the driver, make sure it complies.

I'm fairly sure mine is the common OMP or maybe Sparco -- definitely be sure it's the right type with the alternator circuit. Vastly more work to remote-install but that definitely is better, having it over by the driver's side a-pillar/cowl. Mine is near the battery tray though. Most astute clubs / tech inspectors will test it so be sure you do, including at above idle revs...

These are a bit expensive but very good: https://www.cartekmotorsport.com/battery-isolators/

I always liked these, but not sure about typical track legality. We've run them without issues but they aren't very common. Much better built than the typical cheap Sparco, etc.

Thanks Mark and 914 friends. Got one from Pegasus overnighted. one with alternator protection, worked out well. Best, markhttps://www.pegasusautoracing.com/home.aspClick to view attachment Click to view attachment

Looking good!

I have that one too. I mounted mine next to me behind the shifter and then ran a pull cable to the the same area you put your switch. I just did it on the drivers side incase I had to do a quick exit and forgot to kill the car.
Looks good

I also use one of these

Be sure to insulate those hot lugs. Otherwise you may have a shower of sparks.

Thanks buz914, will do. Mark
