Need watertight male and female plugs that will support 24V/130Amp

[TOBASH]

Starting to dissect and rebuild my HMMWV PCB. I want to find male and female plugs to cut into and attach waterproof to the PCB box. I want remote switches and pushbuttons that will support 24V and 20amp, with 8 guage wire. I want to place watertight plugs on the side of the PCB box, and run low current 24V wires to the box via a plug, with push button control for glowplugs and toggle switch or similar control to activate the relay via the low amperage "on" wire.

I need diodes that will support 24V and 70amp.

I'm trying to bypass low current "on" wire to relay with a diode and switch, and connect the starter to solenoid wire with a diode and switch. I also will create a separate relay to power glow plugs through the PCB with diode and switch and relay.

What plugs male and female should I buy? Where should I source the plugs to attach to the side of the PCB box in a waterproof manner?

What remote switches and what pushbuttons should I buy and where to source. I want low amperage to the switches but still 8 guage should fit the bill.

Diodes are overkill, but what and where to source?

Finally, what relay to use and where to source.

Later on I will want to buy 24Volt circuit breakers of varying amperages. Where to source?

Thanks In Advance!

This connector almost meets your requirements: https://www.molex.com/molex/product...itle=Introduction&parentKey=sealed_connectors

Only thing it's shy of is it's not submersible...it can survive high pressure steam cleaning, but it lacks the IP 8-rating that is required for submersion. It's also probably stupidly expensive.... What may be a much lower cost and simple option will be to just install a terminal stud on/through the box that is isolated from the housing of the box, then you can secure a ring-terminal on a wire to that stud for your power. The HMMWV does just this in its battery box for the starter. Here's a few from one company I like: https://www.bluesea.com/products/category/27/Feed_Through_Connectors The rating is again shy of submersible, but you should be able to self-remedy that with use of RTV sealant on assembly.

For the circuit breakers, it depends on what currents you need. Erik's Military Surplus stocks a few. Otherwise, I'd recommend looking through the HMMWV parts manual once you know what current ratings you need and see if any of the circuit breakers are already used elsewhere, then someone like Greg 86humwv can ship you one for rather cheap. Of course, the sky is the limit on how many of these actually exist, so if you have any oddball ones, maybe we can help you find that.

As for most everything else, you can source by spec from mouser.com. Here's an example search for push button switches there: https://www.mouser.com/Electromecha...es/_/N-5g30?P=1yxr6k0Z1yyqp3wZ1yyg5u9Z1z0z2y5
