Utilizing the original Column mounted turn signal lever.
Drawing of Column mounted turn signal lever

The above is a simple representation of the internal column mounted turn signal lever.
We have been asked several times if it is possible to use our system, but not use our switches. Specifically, it may be desirable to utilized the original column mounted turn signal lever and switch.
The short answer is "sort of."
The left and right select is easy to deal with. The control module (the potted electronic brick) has terminals for Left select and Right select. The input the module is looking for is a momentary short to ground. Our rocker switch has this as it is spring loaded to the center position. The central terminal is connected to ground (thru the module). The left and right terminals are connected to the control module - Left Select and Right Select. The ground short is momentary because the switch is spring loaded to center.
If you can get to the column mounted turn signel switch and lever, it should not be difficult to change the wiring of it to be compatable with our control module.
The wire connected to the central selector - the lever - is usually hot, and by moving the lever, this lead makes contact with the Left and Right signal wires.
So, what you have to do is change the central connection to ground. The Left and Right wires then go to our control module. But you say, the contact is not momentary. Well, there are a few ways to fix that. It might be possible to modify the lever mechanism so that it is spring loaded to center, but that probably won't be too easy. You can try to remember to put the lever back to center, but for practical reasons, that just is not a solution. One very simple solution is to make the ground connected to the lever isolated (electronically momentary).
You can purchase from us a two wire device ($12.50) which will isolate the lever wire from ground and make the contact momentary.
It goes between the central lever wire and ground.
The drawback is that you will still have to return the lever to center before restarting the signal system. But, if the original snap back function is still working, that will do it for you.

The reset button: the reset button is a momentary short to hot, so just about anything else will do.
4-Way flasher: this is a bit more difficult.
This is a rather special switch, DPDT, push on and push off. If you want to provide your own,you will have to wire it up as per the wiring diagram.

Single Bulb, Two Filament Setups

Some simple lighting setups utilize a single bulb at the rear with two filaments. The larger one is used for both turn signal and brake. This filament cannot work both functions at the same time. Dealing with these systems can be problematic. In operation the signal lever, when centered, ties the two rear filaments together to function as a brake signal. When the lever is displaced, the tie of the two bulbs is broken, so that the flasher only lights one bulb. You will have to keep this in mind when altering the wiring as our system was designed to be used with a system that uses two separate bulbs for turn & brake signal. There are workarounds for this (one is right here). Best to call and get it resolved before you start.
