Depends on the amperage of the Jacuzzi and if it is 120 or 240 volts.
12 AWG. You can run several hundred feet.
14-3 Is the standard wire use for residental smoke detectors.
The key parameter in sizing wire is the current requirement. Once you know that you can look up value in a wire gauge table. The length of the run is important for longer runs because of the resistance of the wire itself. Aluminum wire requires a larger diameter than copper for the same current. Once you calculate the wire size you can then size the conduit.
10 AWG.
12 gauge underground wire or if you think you will ever add any devices to this circuit use 10 gauge.
12 AWG. You can run several hundred feet.
No, you can never mix wire sizes in a circuit.
yes
4 gauge
14-3 Is the standard wire use for residental smoke detectors.
The longer the run, the bigger and heavier the wire will need to be. The AWG number denotes the diameter of the wire: the smaller the AWG number, the bigger the diameter.

10 AWG.
10 gauge wire will only run up to 30 amps
10 is the gauge of the wire, 2 and 3 are how many leads are in the wire. For instance 10-2 wire is 10 gauge with two leads, 10-3 is 10 gauge with three leads.
eliminate the resistor wire all together but you want to run a new larger 12 gauge wire into the same circuit , in order to do that you need to take the fuse box down inside the car and you will see where that resistor wire ties into a big wire in the fusebox, it comes from the ignition switch, you need to tie into that big wire with your 12 gauge wire that you have run from the HEI.
12 gauge or bigger.
