Yes a 10 amp fuse will be enough. I agree with Selahdoor on some things. I've experienced a situation where I didn't have a good connection by just pushing the original connector back onto the terminal to hold the new wire on. A nut was required to get a good enough contact. It usually works. On my first 85 F250, I spliced my manual control wire into the purple wire (I left about 3 inches of the purple wire). Pushing the original connector back onto the terminal worked until the day that I wrecked it. My current 85 F250 was done by a previous owner and uses a nut on the terminal.
I have to say that I read post #23 by the OP as the manual control push button is supplying power, not ground. The purple wire has been cut although it isn't visible in the picture. I will say that ,depending on how the push button is wired, the key position (on or off) may not have any effect on whether or not the push button has power. It can be wired to a constant hot power source and since he's asking about a 10amp fuse, it sounds like it's a separate fuse and may be hooked into a constant hot. Mine is and there's no issues with it (yes it has it's own fuse right after the power source). One more thing. If you have the controller unplugged, there's no reason (other than as a precaution) why you'd even have to disconnect the purple wire. It gets it's power from the controller as the controller acts as a thermal switch. If the controller isn't plugged in, it can't send power down the purple wire at all.
