Reddit reviews 5 Pack - EPAuto 30/40 AMP Relay Harness Spdt 12V, 5-PIN SPDT Bosch Style

clinometer

Removed the radio and capped it with abs plastic, fit it with a usb charger and [four of these switches in different colors] (https://www.amazon.com/gp/product/B001GH1PU0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) using these housings

the switches got to [relays] (https://www.amazon.com/gp/product/B017VDI0GY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) that are powered [by this fuse box] (https://www.amazon.com/gp/product/B00QMTAZ1W/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) that is mounted to the top of the OEM fuse box under the hood.

Those power my OBHS and OBA. Other two switches not in use yet, hoping for rock lights/light bar some day maybe?

Removed the old fog light switch panel, replaced with abs plastic and volume control that goes to an amp that goes to a stereo jack that i just plug into my phone for music.

I'd just get a pack off Amazon like this, includes the harnesses too.

After considering our discussion on this I can tell you for sure what I would do if I were in your situation. Since you already have a solar system in place and not starting from scratch you will need a DC-DC switching power supply to replace the AC inverter. I still have never seen one for sale that is suitable for mining so I would build my own to run a single ant s9 based on the design I have tested extensively running 2 ant s5. The design to run 2 s5 is pulling about 700 watts so we need to scale that up to do about 1400 watts. To get right to it these are the parts you'll need, I'll explain in a bit how it will need to be put together and how I came to this design in the first place. After I get all that out I will try to answer some of the other questions folks have about a fully stand alone system. For your needs you will only need the DC power supply/switch/regulator.

2 of these (note it's a 5 pack so you'll be getting 10 relays total. 8 will be used) about $28

Those three items are an mppt charge controller that will be used to control the relays. The 12v relays which will allow you to safely control the power switching and voltage regulators to make sure the power stays clean so as not to damage your gear.

Here's how it goes together, note that all regulators and relays will be hooked in parallel to allow us to get to the desired total amperage;

• DC 12 volt power bus (battery main) gets hooked to the charge controller, powering it up in the 12v range.
  
• Negative bus lead connects to the regulator negative.
  -Positive bus lead connects to relay pass in
  
• Relay pass out 12v positive lead connects to regulator positive.
  
• Relay 'activate power' leads get connected to 'lamp controller' on charge controller.
  
• Regulator positive and negative out connect to miner power cables (pci-e)
  
  Once this is connected as such pressing the orange button on the charge controller front panel will activate the relays allowing power to flow to the regulators which will then even it out and pass it to a secondary bus which will then have the miner power cables hooked to it and power the miners.
  
  By using the lamp controller feature of the charge controller you get low voltage protection. If the batteries get low (even though sounds like you won't have much of a problem with that) the lamp controller will power down the relays and therefore stop the miners. It will automatically reconnect when the battery charge comes back up to safe level.
  
  The idea is to have all this in a box with cooling fans (12v dc case fans) and size it to power a single miner. This box of parts gives you about a 15% efficiency boost over using a big inverter. The cost of an inverter to do this is about $2000, my solution costs about $300, thus dramatically reducing total system costs and allowing a modular approach that will scale while limiting down time due to equipment failure.

Well IMO you should use relays, since they pull a pretty damn decent amount of amps when they first fire up - so get familiar with them if you aren't already, and google bosch style relay wiring. It's pretty damn simple. You just wire to them, to a fused line to the battery, and then inside to a switch and switched power off ur fuse panel.

I made it all into a harness with both fans cuz I build deutsch harnesses all day, but really the wiring is pretty rudimentary.

I had to grind down the fan studs and chop up the efan shroud CONSIDERABLY (who knows what it's out of, snagged it off the ground at a jy). I found out later I had another stock xj fan sitting around, but I'm pretty sure even those would have slight clearance issues and would need a bit of a hack job, but it ain't hard at all.

What I can say for sure is that the stock clutch fan must be a MAJOR drag on the engine. When you see how much force it takes to spin one, you'll be shocked. My c1500's clutch fan setup is probably 1/2 the drag, if that.

These are pretty cheap and get the job done.

5 Pack - EPAuto 30/40 AMP Relay Harness Spdt 12V Bosch Style https://www.amazon.com/dp/B017VDI0GY/ref=cm_sw_r_cp_api_J6h7BbAHCG8Q8

Pins 85 & 86 go between your transformer and doorbell (doesn't matter which way it's wired). The sensor goes to pins 87 and 30.

Edit to add: any Bosch style relay like that will work. I bought the 5 pack because I was going to use them for my alarm system to convert normally-open flood sensors to normally-closed (which is the only kind of sensor my alarm system can read) but the switching voltage was too high (but ended up being perfect for the doorbell)
