Can I connect the positive cable to a ignition fuze instead of the battery.

I would not connect to " an ignition" fuse. Many of todays cars have a computer controlled ignition, which can be sensitive to voltage changes. However connection to a switched fuse say for lights or something not related to engine function may be ok. Check your fuse panel their may be an unused circuit, most of todays cars are "wired" for many optional features, and some may not be used in your vehicle. A simple grounded "light bulb tester" can be used to probe any open slots in your fuse panel. Make sure that any connection you make has at least the same size wire as the harness you are using.

Will this fit any sylvania fog light?

Yes, Our wiring harness are universal and suitable for all equipment. Please make sure that the voltage and power do not exceed the rated value before use. If you need any help please feel free to contact us.

putting this on a 68 mustang and what to change out switch. what are the three colors, blue, white and black for?

Dear customer, This plug-in wiring harness can be used normally after connecting the power positive and negative poles, and the button has only two options of on and off. The white, black and blue three-wire connectors can be used to connect other switches, such as the stobe switch in our store, asin: B08HQGFY8L. If you don’t need this function, you just need to ignore it and use the wiring harness normally.
