You are looking to replace a fuse with a switch?

No

Just put a simple switch in line to whatever. You can buy them from eBay for cheap with a diagram that tells you positive negative signal or positive negative only.

I'm not sure what you mean. Do you have an example?
Is something like this not a reasonable solution?

That's inline. That would be the ideal solution. Initially I read that as remove the fuse and add a switch. That would be a good way to burn your car down.

That SHOULD work. I've wired many a jeep that way for various accessories. Winches, trail lights, elockers.

I've never done it with an integrated system but in theory it should work. Or freak the bcu/bcm out.
