Agreed. I had the same problem and did the same fix. With a toggle, you have to have a good memory whether it's on or off otherwise you risk the following:

1. Starting off in first OD.
2. Breaking the trans if you accidentally try to start in reverse OD.
3. Killing your battery or cooking the solenoid if you leave it on while parked.

BTW, the reason my OD failed in the first place was due to a voltage drop in the solenoid power line--- it happened at night when my headlights were on. Those things don't like to activate if voltage is less than 6 volts.

And another thing, always put a fuse inline if you decide to hard wire it.
