I'm looking for a detailed schematic or even a picture of all the connections for a neutral safety switch/back up switch for a 68 Camaro with console and Muncie 4-spd. I did some searching on this site but didn't find exactly what I was looking for. Feel free to point me to the appropriate link or location for this information. I have the backup lamp switch extension (American Autowire pn CA70554) as well as the bracket that holds the switch (from a spare Muncie shifter). If the car was not originally a 4-spd car or even have a console, is it necessary to replace the under dash harness or even the junction block at the firewall? I guess what I am looking for is a picture of all the components needed to basically get my back up lights functional in order to pass Penna safety inspection.
Thanks!

Was it a automatic or manual transmission from the factory.

From what I can tell an auto 6. But I am intending to convert to V8 manual.

The automatic used neutral safety switch made with backup switch as one switch. The floor shift manual transmission did not have a neutral safety switch in 1968. It used backup switch that was bolted to the side cover on the transmission which had two wire harness that connected to a plug thru comes thru the firewall. The harness under the dash is not the same between automatic and the manual because of this. If you have a 1968 assembly manual look on page 323 it will you how the 4 speed backup switch mounts. Hope this helps

The following pic from carswitches shows the relative setup (although this is listed as Nova/Impala/Caprice), it will give you an idea about how the switch mounts to the Muncie (with a Muncie shifter mounted alongside. Nice clear shot -

Thank you so much for that picture. That is awesome! Now I know how to hook mine up on the M21.
