68 4 speed back up light switch mechanism

I have an early build 68 Z28 4 speed car which I bought in pieces and has been undergoing a 2 year full resto. I've been learning about the car as I go being a Z28 and have pretty much got it nailed as the car is now all going back together.

I'm now at the M21 Muncie and hadn't really thought about the back up lights until now. Firstly I assume all cars had back up lights fitted and working as standard when they left the factory?

I have looked at a friends 69 4 speed car and this seems to have a small bracket/eyelet that comes off the bottom of the steering column where I assume the original back up light bracketry would have attached to, although now all missing on his car as it did a fair bit of racing in it's time. Having inspected my steering column which I assume is the original from the car and I have no reason to think otherwise this eyelet bracket is not there, is this normal? I have also looked at a 6 cylinder 68 convertible and that too has no eyelet type bracket on the bottom of the column either?

I have seen on other post's a reference to a back up light type wiring cable which runs from the gearbox to the firewall then into the car. What determines what your car should have had originally i.e bracketry or wire and more importantly does anyone know what mine should have being a Z28 if that made any difference.

Any thoughts/comments would be greatly appreciated.

68 Z/28, Teal Blue

Re: 68 4 speed back up light switch mechanism

In '68, back-up lights were an option.
All 4-spd trans equipped cars have the switch mounted on a bracket using two bolts of the side cover.
You're right, the harness went from the switch through a female receptacle next to the gas pedal on the firewall.

Good luck on your build.

Re: 68 4 speed back up light switch mechanism

I am also building a 68 convert and have the same issues with the back up light set up. I ordered the parts from Ground up and am waiting for them to arrive. I have both the outside harness and an extesion harness for it. Does anyone have a picture of the bracket installed? I need to know the placement of it. Thanks for the info. on how the wiring gets into the car.

Re: 68 4 speed back up light switch mechanism

All 1st gens had reverse lamps. To the OP, the 69 you looked at had a switch mounted at the bottom of the column, which went along with the new for 69 safety interlock system. The transmissions for 69 all had a backdrive rod linkage which turned an internal tube within the steering column, so that the transmission had to be in Park (autos) or reverse (manuals) before the internal tube was in the correct position to allow the key to be removed from the ignition lock. For column shifted cars and floor shifted manual cars, the reverse light switch sat on top of the column with a tab into a slot on this same tube inside the column. Totally different system than 67-68, but I figured you might want to know why the 69 wasn't the same...

67 and 68 floor shift manual cars have a reverse lamp switch mounted on the driver side of the transmission case, attached with a small diameter bent rod. Good pics of the trans mounted switch in the two threads linked below, both from Farm Boy's setup. The wiring then connected to a plug on the firewall under the wiper motor; there are pics of that here too. Let me know if you need links.
