You might want to pick up a wiring harness adapter so you won't have to cut the OEM wiring harness. The adapter's wires are labeled correctly so no guesswork.

Seems like Mazda's color coding is standard as well - so you might look up which color is power on one of the self help websites.

Yeah, just get the adapter.

But I do know that on a 91, the thick blue wire with a white stripe is the 12V power supply wire.

If the problem is you can't get constant supply and you are losing your presets when you turn the key off, then run a wire to the hazard light fuse, it always has power regardless of where the key is.

Why don't you just find a continuous power line that comes into the car, for example, the line that powers the security light on the center console... put a fuse in there and then run a wire right under the console and up the head unit!
