when these fuse are inserted is this a open circuit ???

Yes, These are just extensions of the fuse socket , so you can attach a fused wire loop and attach a current clamp and measure current of the circuit. I use them to diagnose a suspect circuit.

What is the highest amp rating for these?

The large ones can go up to a 60 amp circuit like a fan motor the smallest is from 2 to 30 amps

Will it work on a 1999 Toyota Tacoma perruner v6 3.4l 5vzfe engine

If your vehicle has spade type fuses then yes it will work on your vehicle. This works on spade fuses only, it does not work with glass or bullet type fuses.
