OK now Im confused. I have been working on this way too long and its time now. After talking to many people on this site Im now ready to install my trans. I went to ground up (temp re-pop) for the linkage on my 4 speed 70 SS to controll my reverse lights. My question is, can I use this linkage if I have the Hurst shifter and not the original Muncie? I also see a reverse light switch that goes on the shifter for hurst in the Ground up catalog. Im wondering if I spent money that I didnt have to. Another question, is the reverse light switch and the nuetral sefty switch all in one? If not can you please explain? Im mostly confused on the switch and if its 1 switch for nuetral safty and 1 switch for reverse or is it 2 seperate switches. I need someone to explain whats what and where they are located. I know one is located on top of the steering column and I think thats the reverse. But where is the other and how does it work? linkage? wire colors? I have started my car before in gear and it jumped into my tool boxes, it cost about $1800.oo in paint work to fix so this is a must. Thanks to all, Jason

Leave it stick, real hot rods have three pedals!
The "neutral safety switch" isn't really a neutral switch, like Dean stated. On a stick it's attached to the clutch pedal so you have to push the clutch in to start the car.
The reverse switch is usualy on the shift linkage. On some cars, it's on the transmission itself. Yours is on the linkage. You can modify any pressure switch to fit your application. All you have to do is make sure the plunger is pushed in when the shifter is in reverse.
On my Dually, I used a nitrous trigger switch for my reverse lights. I just made a bracket that held the switch next to the shifter when it was in reverse, then I drilled and tapped the shifter, and put in a bolt, ground down to a bump that would contact the switch when the shifter was in reverse. You can do this at any section of the linkage, so long as the switch will only activate when the trans is in reverse. ie: shifter handle, shift rod, shift lever on the trans, etc.
Clear as mud?
Good.:thumbsup:

Jason, I assume the 70 setup is the same as the 69. There are several components to the backup light system.
- There should be a "coupler" on the steering column under the hood near the firewall.
- There should be a "swivel bracket" on the frame just behind the front wheels.
- The "backup switch" itself is in the steering column on the inside of the car near the floor.
- You will need one "linkage rod" which goes from the side reverse lever on the transmission to the swivel bracket on the frame.
- You will need another "linkage rod" which goes from the swivel bracket on the frame to the coupler on the steering column under the hood.
The system works as follows - "When the transmission is put in reverse, the rod from the transmission turns the swivel bracket, which in turn forces up the rod to the steering column coupler. This in fact rotates the entire steering column which activates the backup switch. All the wiring for the backup lights and switch is part of the normal wiring harness."
Yes, this will work with a Hurst Competition Plus shifter. You may need to do some fine tuning and adjustments with the rods from the shifter and the side reverse lever.
Hope you can understand this and it helps.

The back up lights are driven friom the back drive linkage to the column lock. When the collar on the column and the lock rotates to "reverse" it activates the switch at the base of the column. A hurst shifter will work if you have the correct reverse arm that accommodates the back drive.
All of this assuming that you have the back drive and column switch.

I installed a hurst shifter in my 70 ss with a muncie m-21. I then hooked up the reverse lock out so when I place the gear shifter in reverse...two things happen. The colume will move and the reverse switch located on the bottom of the steering colume turns the reverse lights on...it also allows me to remove the ignition key. Also, I hooked up the nutural safety switch located under the dash connected to the clutch pedel...

Most of the responses so far are explaining the use of the linkage rods which were the original equipment on a manual trans car. If you are not worried about being original then you can just hook up your reverse lights with the Hurst switch you saw from ground up and then you dont have to worry about using the linkage etc. The switch gets mounted to your shifter so that when you are in reverse the plunger (on the switch) is engaged. From the switch you run two wires to the revrse switch which is mounted near the bottom of the steering column. This switch has a pink wire(power to the switch) and a light green wire (power to lights) . Hook up wires between this back up switch and the Hurst switch on the shifter and you are done. I am not positive but I believe that the original linkage cannot be used if a hurst shifter is installed or if headers are installed??????

OPG has the correct neutral switch for the 69. I have a 71 which I just changed over to 4 sp and the pedals I bought were out of a 69 and came witht the factory switch. I just hooked the correct wires to the switch lead wires and it works excellent. Clutch pedal to the floor to start. I haven't decided on what switch to use for the back up lights yet, but it WON'T be the rods.

Exactly what I would do if mine was to be original
