Hey Y'all
I didn't use Brian's suggestion about relays, but the size of the high amperage cable and switches quickly made me regret it. (The switches won't fit in my red remote enclosure!!
)
I started over from scratch using relays and I like this much better.
NOTES:
1. As Brian suggested, the OEM switches are still on high current wiring as a backup to the relays. I chose to wire them off the relay posts rather than the other way around. You could wire both off a terminal like Chris R does.
2. I use winch relays because they're cheap and can handle the load.
3. I couldn't find cheap waterproof STDP switches, but eBay has inexpensive waterproof DTDP switches. I use "half" of each DTDP as a STDP.
4. I prefer having connectors at both ends of cables. They're easier to store and reduce the wear and tear on the cable. You could save money by hard wiring the cable to the remote with a cable bladder.
5. The remote housing has a waterproof RJ45 connector. You can use a second one in the storage bay, but this connector is sheltered so it's probably(?) not needed.
6. Two sets of switches are wired to the relays in parallel, one located in the front storage bay and a second set on the remote. Only one set is needed. You could include both or just one.
7.
Not in this design: if you put a third switch on the remote, you could use the two switches to extend each jack separately to the ground. The third switch could be wired to extend both jacks together. I'm not sure this would a good thing, but it's an interesting idea
I'd appreciate any suggestions and/or corrections you have. When it's finalized, I'll post it here with a Bill of Materials.
