How many of you who run the TF in their track only car use the factory NSS and how many use the NSS in their aftermarket shifter?

I use the OEM unit with the switch that has one terminal / nut which the wire fastens to wire to starter relay done deal.

I just switched to using the one in my ppp shifter. Works perfectly.

use the factory switch/ground.

factory switch using center post of three...Sure would like to find old style single post/nut. Anyone have a common source or supplier?

I use the factory, altho I do have the PPP

On my car I use the one that's in my B&M Pro Ratchet shifter.

I just hooked up the factory one in Gina's 72. It had an aftermarket soliniod on the fire wall so I installed a relay that's gounded by the factory NSS to energize the soliniod only when in park or nuetral.

I am using the factory switch

My shifter is PPP I use the furd solinoid mounted in the rear and had to find the correct one to work with the factory neutral switch

Factory 3 wire switch. Only using middle wire.

factory nss on all..

Not implying that it's "broken" but the need for a relay and the rarity of the '62-'68 NSS would make some want to use the onboard switch in most aftermarket shifters.

For those, I'm trying to determine if there would be a market for some #8 NAS plugs for the switch hole that I might be able to get in quantity.

3 prong here ,center for grounding starter switch outer 2 for activating trans brake for reverce

The Nuetral safety switch on my 727 came off a neon. Steve
