    Default changing wire gauges question

    I am getting to run my wide band o2 to my megaquirt.
    am using an existing ignition 12v wire, but it is larger than the wide band 18 gauge so I decided to put a 5 amp in between, but the 5 amp fuse wire is 12 or 14 gauge. is it okay to go from a 12 to 18?

    Thanks

    Basically electric wires are like water pipes, only they convey electricity.
    Several gauges big to feed smaller ok.
    Fuses never hurt except for adding more connections that can fail.
