neutral saftey switch

got a 69 dart 3 prong nss harness and a 727 with 1 wire nss from 70 Newport. I have read conflicting post on Google where some say you can put a 3 wire nss in trans and its fine but others say it won't work. Can I do that or what other options are there? I could wire the middle wire to it and it should work? Just wouldn't have reverse lights?

There's a slight difference in the 'rooster' bracket inside the trans that triggers the NSS... I believe that there are two different rooster brackets for the three prong NSS... You need to find out what rooster bracket is in the trans and get the proper three prong NSS to work with it...

It's been a few years since I ran across this...
