I have been running without my alternator for a couple months. I just disconnect it, wrap the ends against water, and go. If I run too far or too low, I go through the slight pain of popping the hood and reconnecting. I want to plan and install a kill switch. I need help.

Where can I cut in for the splice for the switch without damaging the alternator? And can I do it at the fuse box inside the cabin? That would be much easier in terms of routing, but I doubt it is effective and safe for the alternator. Thoughts?

Here is, I think, the appropriate wiring diagram from the Honda Service Manual. I have checked all the wires and the color-coding matches. The wht wire is a heavy lone wire and the four others are bundled into a 4P connector [EDIT: The ECM/PCM ("ECU") is in the cabin]:

I am aware of Daox's mod, but I am uncertain of what line into the cabin I might safely use on my civic. The wht/red line from the 4P connector seems like a candidate.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
