Well today Iím at a total loss on what or how the back up light switch was hooked up. Why, because where the AIM calls out a .920 to .940 diameter hole to be drilled (dimple location) there is no hole in my cowl. I think I found the dimple or at least it seems to be correct and the NOS underdash mat has a one inch or so hole located where the dimple is. Can someone please show me what they have on their 4-speed 67 or 68 Camaro? When I purchased this car over 30 years ago it was already tore apart so assembly has been, letís just say FUN.... LOL......
Some references: What the AIM calls out for 3C which I think is for the back up harness-
What seems to be my dimple (hard to see in a pic but prominent in person) that has no hole located under the ground strap and zinc screw-
The connection between the two harnesses that is supposed to connect at the firewall-
