Considering setting up a reverse light and was wondering what ideas others had for installing a switch to intiate a reverse light and still retain the original look. I would like to install this as a microswitch on the shift tower , but looks like the shift rods would put the light on in different gears beside reverse.Have considered a switch on shifter or a prox sensor or magnetic switch but with all the metal, tossed that idea, or a mercury switch. How would you guys do it, lets see some sketchs. , . |

If you can find a late model T90 and maybe T86 shifter assembly, they have a threaded port which accepts a screw-in switch with a small ball on the end. When the ball comes in contact with the shifter rail (for reverse) it makes contact and activates the back-up lights or whatever is on the wiring circuit. I have seen the shifter assemblies out there and do know they exist. That would be the most efficient and reliable method I would suggest. Good Luck with your project, Sam Michael Jr, Jax, FL |

I like the cj3a page idea and kinda what I was thinking about, and now it makes the best sense. Just have to rough one out first for a template

Just be aware that you are potentially creating another source for a gear oil leak by removing the shift rail cap. Our Jeeps leave enough "stains" as it is. Let us know how it turns out, Sam Michael Jr, Jax, FL |

Most of the T90s I see in my shop are missing the shift rail caps anyway. |

You're correct and the missing caps cause leaks - that's why some folks resort to fabricating a flat plate with a bolt in the center to seal both holes at the end of the shift tower. |

I did it the easy way. I added a pull type switch on my dash next to my light switch and ran it directly to a reverse light in the back. I mounted a front running light over my existing brake light housing, so it looks kind of like it was meant to be there. I just pull out the switch when I'm backing up. The only problem is making sure I remember to push it back in when I start forward again. |

I have mine on a toggle switch on the dash, I turn it on when i need it. Comes in handy when you need some light behind and the jeeps not running. |

Well, seems my shift rail caps are already missing and the 2a idea is still sticking with me along with the toggle on the dash. So I'm going to combine the two ideas and enable the light with either.As a safeguard[goof proofing] thinking of including a mercury switch inline with the dash. Idea being if switch is left on , when forward motion is intiated, the mercury with relay will open the circuit and keep the light off. Like the ideas guys and thanks for the pointer to the 2a shifter. |

Back in the day (60's) when reverse lights started to become standard those of us with older cars would buy reverse light accessory kits. At that time local law specified, for obvious reasons, that the dash mounted toggle switch had to have a light along side it to show that it was on. A simple fix that was very popular, served a purpose and worked quite well.

I went with fabricating the bracket like in the pic on the 2a site and I like it. Now how I will route the PVC coated wire away from the heat is my next quest. |
