Neutral safety switch 4 speed
Neutral safety switch 4 speed
I have a 68 4-speed Cutlass and have never found a neutral safety switch. I've looked in the chassis manual, assembly manual etc. where should it be? On the clutch pedal?
GM Standard Transmissions did not start using a safety switch until 1973 (IIRC)... In 1973 & later years the clutch pedal had to be depressed in order to start the vehicle.... This is not the case for pre 73 vehicles....
If you try to start an AT car in gear with the neutral switch disabled, what happens?
If you've got your foot on the gas, it roars to life and drives through the back of your garage, or through the crosswalk in front of you.
Neutral safety switches were recognized as a necessity very shortly after automatic transmissions were invented. They were not included in MT cars until the new safety regulations that took effect progressively beginning in 1968.
Your '68 never had one.

As a matter of fact I lost a dampening spring on one of my clutch disks and it got wedged between the pressure plate and the disc and the clutch would not disengage so I had to start it in gear so I could drive it to the trans shop.
Granted none of these were domestic vehicles, but that's not the point.
If I started any of these in gear they would start moving with little difficulty.
I added the '69 up clutch safety switch to my '68 "just in case" I had the clutch pedal on my '67 442 break on the way to work back in '79. I was half way there so I kept driving it,starting it in gear at stop lights,it started in gear very easily. I had a set of pedals,complete with the safety switch that I took out of a '70, in my stash of Olds parts,I figured why not use it since everything bolts right in,including the wiring. You have to have the later clutch pedal with the pin on it for the switch & you'll need the short jumper harness that goes from the cars harness(double purple wire connector by the fuse box)to the switch. All the parts are easily obtainable these days from the after-market.In-Line even sells the jumper harness. I figured it was a sensible feature to add to the car. The '69 assembly manual shows a good pic of the switch assy. in the trans section.

OK, first of all, there is no such thing as a "neutral safety switch" for a manual trans. It's a CLUTCH safety switch that operates off the clutch pedal and has no relationship to whatever gear the trans is in.
Second, back before product liability lawyers took over the world, it was given that operating an automobile required COMMON SENSE. One of those common sense elements was that you had to step on the clutch pedal BEFORE you tried to start the car. Kinda the same common sense requirement that you don't start the car in a closed garage.
Unfortunately, the American public always requires someone ELSE to be responsible for their mistakes, which is why GM cars got clutch safety switches starting with the 1969 model year.

My '68 has no clutch safety switch. If you turn the key and it starts and its in gear, its leaving.
I had a '92 'Yota HiLux (pre Tacoma) pickup that had a clutch safety switch 'over ride button' on the dash. If you pressed it, it would defeat the clutch safety for one start cycle then reset. I don't remember ever using it so I'm not sure if the engine would fire. It was in the manual as useful if you had to do something like get it out of an intersection using the starter motor.

I need to get one of those for my Tacoma. Once I get my Tahoe up to daily driver specs, the Tacoma's going to get a mid-life crisis and I am going to fix a few things.
In the winter, I open the Tacoma, and remain outside. I lean in, put the key in, put the clutch to the floor with my left hand, put it in neutral with my right, then crank. After it starts, I let go of the clutch, adjust my defroster, then go to work with the scraper on the ice. Would be nice to have the clutch bypass switch, but not really all that important.
I believe the idea was to crawl out of mud on the starter motor, or some jacked up stuff like that.

Don't know the year of your Taco, but Toyota used this switch on many trucks from like '85 - '05. It was usually labeled "Clutch Start Cancel". Get a switch (several on FleaBay) and it should be almost plug-n-play. It has 3 wires. Probably 2 are to jump the actual safety circuit & the other is feed from start that resets the switch.
It's a 7. There's a pretty good pull a part here in Evansville I'll hit up for some various things next spring. Used to be better until they found a meth lab in it, now most is they-pull-it. 
I'd have no issue with a dumb "hold that thing down while cranking" switch.

The advantage to the Toyota piece is you click it, it lights up (IIRC) and you can attempt a start without pushing the clutch or holding the switch. After that attempt, it automatically resets so you have to click again for another attempt. This way you don't 1. have to hold the switch & 2. have to worry that the next person will attempt a clutch-engaged start.
Yeah, Indy, you're right. It's not high on my list of stuff to do, but I'll get it done along with swapping out the headlamps, prettier grille, might go to matte black fender flares instead of the color matched, and a general paint repair and polish job.
Packrat, I did not know this, but apparently it was in a dumpster!
