Working on the '50 coupe today I realized it doesn't have a neutral safety switch and cranked it in gear, fortunately out of force of habit, my foot was on the brake and nothing & no one was hurt. So this is something I need to fix right away, In the past I have had a steering column with a built in NSS or a aftermarket shiftier that had one, this car has a early style mustang automatic shiftier and I don't see any provisions for the NSS on it. What are you guys using when you have a original column? HRP
You could use a 1950 Chevy truck brake switch and hook it up and mount it so that it works for the clutch arm so you will have to depress the clutch for the car to start
Easiest thing I've heard is a quality switch activated by clutch pedal. So a simple 2 prong switch mounted on a bracket in series with ignition switch crank position, will only crank when pedal is depressed. My truck is adjusted so pedal is almost on the floor.
Pull that shifter up and take a better look, I ran a '65-ish Mustang shifter in my '57 for years with a NSS.
Ford trans are made for a switch to bolt on over the shift arm,I do have one on my sunliner that is hooked up and also put one on my 66 F100 but it was mainly used for reverse lights and the NSS part has not been hooked up and might never be.
This. The switch should be located on the transmission, and is actually the best method as it doesn't depend on shift linkage adjustment. It may even be there, just not hooked up. You should have four connections, two for NSS and two for backup lights. If the switch is functioning right, you can start in both park and neutral.
since you have already started the car in gear you no longer need the neutral safety switch since now your brain has been trained to check before starting the car. I only had to crash into my sandblast cabinet once in my old 49. never did it again. same thing when a shifter had no type of stop before putting it in reverse while driving down the road. one time was all it took.
Okay Danny, a C4. Take a look at where the shifting shaft comes out of the transmission. There should be a pair of threaded bosses there to mount a neutral safety switch. If you need one I’ve got a brand new one in the drawer in my garage. They’re around $60 or so by the time you get them in your hands. If you need it let me know. Larry
That switch that Blue one posted should be the correct one. If that shifter is like the Mustang shifter I had in my T there are no provisions for a neutral switch. Someone used/uses that Ford switch in their neutral safety switch kit for Turbo 350/400. Real simple real reliable.
Danny another way, sometimes used over here by some guys is to use a relay, and wire it in as per this drawing. You have to put your foot on the brake before the starter will engage. Only a suggestion, not everyone's cup of tea.
HRP, Lokar makes an electronic switch that I used on a couple of cars. It is cable activated from the transmission shifter shaft, the box has hookups for multiple options (neutral safety, reverse lights, gear indicators). I is easily hidden. I have had one on my 442 that I added a Hurst dual gate to that had no provision for neutral safety or reverse lights. That was several years ago and it still works like a charm. Not cheap though. That aluminum box is mounted to the transmission (I mounted mine on the right rear pan bolts) , the cable runs around to the output shaft. The harness connects to that micro pin box which is circuit breaker protected. I tucked that box under my console. To that box you connect your reverse lights, ignition interlock, etc. On your mustang floor shifter you could add gear indicator LEDS under the lens from this device. Just an option.
Larry, the car is off the lift and I'm working in the trunk now, but I will get back to you in the near future and let you know something,I working on repairing the trunk floor and trying to fit the original replacement '50 gas tank. HRP
First I do not normally put a NSS on a manual trans car. On an AT car I wouldn't be without one. Lokar makes a ball type switch that has a bracket to mount it to the pan rail. I have used this one extensively and find it top shelf. I believe it sell for about $59.
Had an excellent example of why you need a NSS today.... Went to 'Wounded Warriors' type show (although they don't use that name anymore) and as people started leaving, a guy in a 'rat rod' VW hybrid (Beetle body on a hot rod ch***is) started his car and immediately ran across a walkway and into a super-clean survivor 64.5 Mustang convertible. The VW caved in the Mustang's lower valance panel under the bumper, also taking out one turn signal and springing the bumper. That was the front of the car... it also shoved the Mustang into a chain-link fence, scratching up pretty much the whole back of the car. VW owner's excuse? 'I don't have a NSS hooked up yet...' Luckily, the VW owner said he has insurance.
