    Default wiring diagram

    I saved this about 5 years ago, knowing that it would come in handy one day. If I remember correctly it was courtesy of Tom at Jetboatperformance, THANKS TOM!
    No wire size, but hope it helps.
    Be safe, schick

    For what you have listed: Alternator 10 Ga. Fuel pump 14 Ga. Starter (I assume you mean the sol. connection 14 Ga. Bilge pump 14 Ga. instruments 16 Ga.
    For the fuel pump, I would use a relay. Just my opinion, after wiring several street rods and boats. Also I might suggest that you use non-insulated terminals with
    shrink wrap tubing if you want a really clean "look". Slide shrink tubing onto wire (1 inch long) then install terminal and crimp. Next, slide shrink tubing over crimped
    area of terminal and apply heat to shrink tubing. (I use a heat gun) Hope this helps you.

    I would agree with the suggested sizes and the use of a relay for the fuel pump.

    The use of MARINE WIRE, such as Ancor is also a very good idea.
    There are several reason to use marine wire with no down sides.
    The MARINE WIRE should be of the tinned type, as it help resist corrosion.
    It is more flexible than automotive SAE wire and even though both may say what gage wire they are, the same gage MARINE WIRE will carry more current.
    Marine wire contains more strands of wire which makes it more flexible and why it carries more current. Marine wire also is made to withstand the marine environment and chemicals used around boats.
    Do not use any wire that is a solid core wire similar to what's used to wire houses. It is not designed to withstand vibration and will crack.
    Color coding is a must to save your sanity while wiring, and in the future if you make a change.

    It does cost some more, but it's a one time item.

    Do you solder all connections or just crimp ?

    Coast guard say crimp connections only. 14 gage is good for all circuts.. Some circuts will need a relay

    Several street rods that I have done, I crimped & soldered. Because of the vibration involved with boats, I would crimp only.

    So the battery is at the transom and I'm running two leads to the center console POS and NEG and using like a 8 terminal bus/junction block X 2 one for neg and one for pos what gauge wire should that be ( thinking like 10 gauge)also on the bus/junction block I see that there amp ratings on them, which amp should I get,and there on the wiring will be 14 Gauge to switches. junction block will be riveted on the underside of panel the tabs are on for future access to wiring and the oil is Mechanical.
