Hey Guys,

I have been looking for a reverse switch to go in a M21, does anyone have an idea where I can purchase one? Or, another idea of the best way to hook up the reverse lights on my 67 RS?

thanks a lot

The standard backup light setup mounted a switch with a bracket to two of the tailhousing bolts. It connected to the reverse arm with a link. Your reverse arm would have a small (1/8") hole to accept the link.

The switch, bracket, and link can be bought thru the repro houses such as Rick's.

Another option if you have a hurst shifter they sell a switch that attaches to one of the shifter stop bolts. You would need to extend your wires to it.

If you are not worried about having an 'original' type system, and are at all familiar and comfortable with electronics, you can find some of the small Proximity/Inductive Sensors available from several sorces very usefull for these type of uses.
I tend to favor the smaller Omron brand round and square NPN types I can find at any of the surplus electronics stores locally. But you can also order a specific sensor throught places like Digikey on-line.
Some of the higher end parts have adjustable sensitivities that make mounting and adjusting them very easy.
Costs new can range from @$30 up (way up for some) when new, surplus I can get them from @$5 and up.
They are totally sealed and some of them have leads long enough to route into the interior - so they tend to be very reliable and weatherproof.
The NPN type are wired between the voltage source and the item you're going to activate. These NPN are usually the easiest type to install as many auto items use the vehicle body as the ground and power is supplied via the wire into it. If you use PNP type, just wire it between the ground wire of the item and the ground of the vehicle.
I just fabricate a bracket to mount to them close to the item I need them to detect, like the reverse rod when in the 'reverse' position, and then wire them into the circuit/device I need to control - like reverse light circuit to lite the lights.
I have used these on many trucks, cars and boats for sensing throttle, brake and gear positions reliably. I haven't had one sensor fail yet that I'm aware of.

Hope this helps and gives you a few options;

thats awesome, thanks a lot guys!

I will be able to get the lights all figured out now!

A nice toggle switch mounted at the bottom of the dash works well too!

I used the Hurst back up light switch and it worked great. Brad
