The previous owner didn't think it needed the reverse light switch.....any idea what it is supposed to look like and where/how it mounts? All the wiring is there, and to the lights, just no switch and connector. Thanks, Josh | | |

When I got the truck, it had the cutouts in the back for the lights, and a wire from the harness to each empty hole, and this funny little tab at the base of the stick shifter just inside the cab with a green wire sticking up through it. So I figured it used to have one that the previous owner removed along with the tail lights. I have the lights in and the wiring in place up to the tranny....just need the switch | | |

I remember the green wire that cowinfog is talking about.My switch went bad, and i could not find a replacement.I know it kind of looked like an oversized glove box light switch.I sold the truck,when gathering all the parts that went with it, i did not find it.You may want to try to get a hold of lilred66 and see if he has one.He is very knowledgable about the 64-66 trucks,possibly may have what you want. 1951 3100 Chevrolet1951 Chevrolet Suburban CarryallImage"A house is built with boards and beams.

The reverse lights became available in 1966 on these models. Attached is a picture of what the assembly looks like. \'66 Chevy Truck Reverse Light Assembly I hope this information is helpful and clears up the availability issue of reverse lights as a factory/dealer option in 1966. bowtietim, thanks for the nod. | | |

#95129 03/28/2006 1:08 PM | Joined: Sep 2003 Posts: 343 Member | | Member Joined: Sep 2003 Posts: 343 | Steve, According to my SM420's date code it should be a 1967, but mine does not have a reverse switch installed in the cover. I will have to look for the thread on this subject, it would be nice to have reverse lights on my truck.
