How does this contact to a power source?

They give you a connector kit to put to the battery of your lawn tractor or ATV. Honestly, it was a very crappy connector, so I went to a auto parts store and bought a better connector and spliced it in.

It uses a 12 Volt AC/DC power adapter, 1500 milliampere (MA) output, with a POSITIVE tip (that would be the inside connection)

I don't think there is supposed to be power there, I think it is only supposed to switch power you bring in. I'm not positive, but that is how I'm using it.

I had to provide my own power source. Power is not wired to these points on the circuit board. Start with a simple continuity test using an ohm meter.

It needs to also be tapped into a 12v source. Mine is installed behind my stereo.

See Dan's answer, and the power connector is a small cable that plugs into the board on the device, that adapts it to the 4-pin connector to your power supply.

The relay contacts do not supply power. You use them as a switch for the power you wish routed through them.If you are that unfamiliar with power control devices, then you may consider not working with high voltage circuits.This is pretty basic stuff... the relay closures are not a switched AC outlet.

This is a delayed contact closure, not a power supply. You have to supply power for it to work.From the picture it can handle upto 10A. Your led only draws 2A.

It is supposed to connect to its own card.it came with no power supply specs.i used a 12 power supply but could not get it to work.waste of money so far.no info came with unit.

No you do not - simply connect it to the GPIO headers on a raspberry pi. The connector on the bottom is where the unit draws power from.

the way I wired it was simply power and ground. I wired it to a relay first then a switch. its really basic

It connects directly on top of your battery terminal and the back you connect you existing cable. When you unscrew the green knob, the power is cut from the battery to the vehicle. Very simple. If you are leaving your vehicle for any length of time, you might consider a "battery tender" to keep the battery from going bad over time without the vehicle being run.

It has an output contact that you could use to trigger an external system, but I have not tried it to see how it works.

Whatever power supply you choose to connect it to. This is a simple connector with + and - leads on the back.

The electrical connection must be made at the outside unit. it will feed the electricity to the inside. The connection at the outside unit should have a disconnect so that you can cut power to the unit

As indicated by other reviewers, the solar panel connects to the left two terminals. Battery to the middle two. Be sure to observe proper polarity.

No, it doesn't have to be in contact with any surface. It is simply a switch that connects in series or connects a circuit.
