You would have to take apart the switch and make it only signal the driver, the battery lead would bypass it. I'll see what I can find, it would look similar to these momentary switch mods, without modding the plastic black lock cam in the switch.

I had to borrow these pictures from the above threads, these by Will and Freddy.
Here is the "+" wire that will bypass the switch:
Now solder it to the spring, this is your full time "+" to the driver:
Now we need to modify the internal part of the switch to carry the switch contacts needed by our driver:
See how Freddy ran one wire to each of the contacts of the switch, and he installed some nice shrink tube to isolate it from the nearby positive terminal.
So now you need one more wire to the ground,
A total of 4 wires, one full time "+" to the spring, one "-" to the setscrew, and 2 wires to either side of the switch.
I hope that helps :o Sorry about using many different sources for the pictures, but the tutorials were for momentary switch mod, you will only need to do the switch bypass mod. One of these days I'll create a new tutorial.
