    Here is a question that is perplexing me. I'm wondering if a 1967 4 speed barracuda would of came from the factory with a neutral safety switch? I'm the second owner of my car so I don't know what has been changed. After looking at my starter relay on the fender in the engine bay and tracing the electrical schematics I'm confused. According to the dart electronic schematics book it shows a stud on the relay where the neutral safety switch attaches. Well my starter relay was made without that stud. Then I went under the car and looked at the 4 speed tranny. I do see a reverse switch but no neutral safety switch. I do remember that I have accidently tried to start the car in gear and it lurched forward when the clutch isn't depressed. Am I missing something or did 4 speed Barracudas not have a neutral safety switch or was it just on an automatic that year? Maybe some things on the car have been changed? Any help greatly appreciated.

    NO.

    Here's the deal

    All manual trans cars came with ONE push - on connector on the start relay until the advent of "clutch safety switches" in 70 and later. Then they used the same relay, with TWO push on connectors, as the automatic cars. So the clutch safety switch was on the clutch pedal linkage

    My 70 (sixpack RR) also originally had a reverse lock on the linkage, IE you had to have the 4 speed in reverse before you could lock the column. My friend that was the first owner had removed the link, and I wasted no time in removing the clutch safety switch. In over 140,000 miles, I never once "needed" all that junk

    Earlier (68? earlier?) cars with automatics had the NSS on the shift linkage

    Later (69? later?) cars with automatics had the 3 terminal NSS down on the transmission.

    The only thing the 69/ earlier stick shift cars had was a backup light switch.

    If this is something you are concerned about, I guess you could easily add it. The clutch switches were not run through the bulkhead connector, but rather through a separate grommet. So you could buy an "auto" start relay, add a wire and rig a switch to the clutch pedal.

    Thanks 67Dart273

    So basically someone removed it. What is on the car now than is an automatic starter relay without the push on tab for the clutch safety switch to hook up to? I guess I could just leave it as is instead of rewiring the connection from the clutch pedal assembly to a new 4 speed starter relay. The only difference being that the car could now crank over when in gear causing it to jump if clutch isn't depressed. Just so I understand does the correct 4 speed starter relay have 1 extra prong for a push on connection or two? If I'm wrong please explain. Thanks for the info. That's why this site rocks.

    No, you missed the "deal"

    Before 70, stick cars had NO safety. The three terminal start relay is correct before 70, for stickshift cars, like this:
