Happy New Year new member here. I just swapped in a 454HO with a Hurst 5 speed and I loose the reverse lock out feature but the tranny has a neutral safety switch.   

What I would like to verify is that the 74, manual trans vette  has a reverse lock out and a clutch pedal safety switch and not a neutral safety switch. Requiering you to have the clutch pushed in and the trans in Rev to start. or at lease get the key key in and out.  Ooh and also the seat belt interlock that everybody has bypassed.  

In my research, from various sources, I believe that the reverse lights switch plug is being identified as the neutral safety switch plug by the style of plug and red and green wires. 

I am debating weather or not to bypass the neutral safety switch or incorporate it. I will keep the clutch pedal safety switch. I don't want to create a habit of keeping the car in neutral. I will miss that reverse lock out feature for that reason.    

Thanks

Reverse lockout is mechanical.  It's the small t-handle under the shift ball.

I'd just s-can the neutral saftey switch.  Never had them before, don't need them now.

NO "neutral safety switch" on the manual trans. Only has the clutch safety switch. Clutch must be down to start.
Reverse "lock-out" requires the manual trans to be in Reverse to remove the key only. This is accomplished via a cable attached to the trans reverse linkage on one end, and the other end of the cable is attached to the lock lever on the steering column, under the brake master cylinder/booster. If you have removed the stock trans/reverse lock-out cable, you will need to tie the lever on the column UP, so you will be able to remove the key. If you do not somehow tie it up, it can move down on it's own.

I would leave the clutch safety switch intact...and make sure it is working. Last thing you want to do is forget to push the clutch in while starting, and drive thru the garage door....or over someone.

hi  note I have been through the door  there is no fun there    not my fault    clutch pedal switch was not reconnect  after painting,   it is now, new door looks fine  live and learn. dwa175

The original reverse light switch is on the trans. It has a light green wire, and a pink wire in the plug. Pink is hot from the fusebox, for the turn signals, lt green goes from the rev light switch back to the lights in the rear. That's easy enough to connect to the reverse light switch on the new trans. Doesn't matter which color wire goes to which terminal on the switch....it's just a simple contact/no contact switch.

Thanks for quick responses 

The NSS on the trans would be a redundant backup....or just redundant, period. In keeping the clutch switch operating, it won't start unless the clutch is down, anyway.
As far as the '74 only ignition lock-out system, you can simply disconnect the seat switches and be done with it, or you can remove the starter override relay under the hood.

That was my thought
