Bypassing the Amp gauge - Question about the MAD Electrical method

Do you want to eliminate all or some of the toggle switches and use the ignition switch?

I would like to keep all the toggle switches. I'm not sure if the keyed ignition switch even works. I asked the POs wife (her deceased husbands car) if the key was needed to start the car and she wasn't sure.

If you want to do it more neatly, you could have a little distribution box on the inner fender.

That's a fine idea...
