Hi guys. I am swapping in a 4 speed to a 67' Skylark that was a 2 speed auto. I need to run a wire to the backup light switch on the Saginaw 4 speed that I am installing. The switch has 2 leads on it so I am assuming it will be in series with the light wiring and it will be normally open and complete the circuit when in reverse. I was going to route the wire on the floor and poke it out near the switch on the transmission. I guess I will have to actually feed two wires or a loop of wire to go through that switch. I am assuming the current reverse switch is on the column shifter under the dash. I have not had a chance to track it down yet. I can not find any wiring diagrams that show any of this. I did spot the reverse lighting wires in the back of the car are light green so I will look to see if the colour is the same on the column harness. If anyone has any info to share it would be appreciated. Thanks. Greg
I've done several auto to manual swaps. I make a jumper (about 2 inch "U") and connect the two purple wires off the neutral safety switch (unless you have a neutral switch off the clutch pedal and want to use it) and the dark green wires for the reverse light. Both are on the same switch attached to the steering column near the toe board. I have the neutral switch that I got with a pedal setup, and am not using it if you need/want one. I grew up with motorcycles and old manual cars and "learned" to not start in gear, even with the clutch depressed.

Thanks for the info. Somehow I missed that one in those wiring diagrams. I am using a Mcloed Hydraulic clutch pedal kit and do not have a clutch/neutral safety switch planned. It is definitely not an issue for me as I grew up running all kinds of cars and equipment with manuals and clutches but this is actually my wife's car so it might be not a bad idea for her. She has had a few manual transmission vehicles over the years but all much more modern. I will do a bypass as you say in the short term then maybe consider adding a switch once we got all the other stuff done. I will pick up some green wire if I don't already have some and run a loop to the transmission switch and back then. Do you usually just run it on the floor under the carpet and then poke it out the floor near the transmission? Greg
Don't worry. I am an aircraft mechanic of 30 years. I am used to dealing with proper wire routing and chafing all the time. It will be protected with a grommet for sure. Greg
Cool. Love the Phantoms. One of my favourite planes from that era. My career has mostly been on helicopters with the bulk of my time wrenching on Hueys. I still work on them every day. Greg
I got no hate on a hundred thousand random parts, flying in close formation, and beating the air into submission! Got a few hours on the UH-1N (626 and 627) on the ranges. Dang. Where did all the time go?
That is what I spend most of my time maintaining, the civilian model 212. I also work on the Bell 205 and spent my early career working on the Sikorsky S58T. They were converted H34s. Here are a couple of the Birds I work on in Fire fighting configuration. Bell 212 and 205. Greg
