Yes. Where does that connector belong? Should be a Letter and number on the board where it plugs in.

To be sure I understand you, this pin came on and you could play a game before you picked it up last night. You hauled it home, put the legs on, and when you stood up the backbox pinched some wires. After moving the pinched wires you turned on the pin and some lights come on but you get no sound as if the game is booting and nothing on the display, just completely blank?

You have a multi-meter, do you have a manual? Page DR. 1 shows all the fuses and their location on the various boards. With game on if you can safely check F8 & F9 for 12v DC and F23 for 5v DC do so.

For future pictures may I suggest removing the fluorescent light bulb and setting your camera to maximum resolution? If we can see focused shots and read the labels on the boards we can better assist you.

You'll want fuses rated for 250v. Auto parts stores often only have 32v rated fuses which will work but can spark when they blow. Home Depot or Lowes will most likely have 250v rated fuses of the amperage values you need.

Your board needs 12v and 5v to boot and run properly. Do you have those voltages present?

Your meter is set to check DC voltage. When you check resistance on your fuses you need to turn the dial to what I've circled. The Arrow points to the Ohms symbol.

Edit: Also, when testing for 12v and 5v you need to move the dial one click clockwise to 20. In the photo it's set to 2000mv, which is too low.
Don't get discouraged We all started somewhere. We'll help you get it going again.

As noted at the link PinballManiac40 provided, installing the NVRAM doesn't require soldering on your Lord of the Rings
You only need to note the orientation of U212 (pictured at the link), CAREFULLY remove it, then CAREFULLY push the NVRAM into the now empty socket.

You don't even need a chip puller - but it's helpful. Don't use a metal screwdriver, you could gouge the board. Popsicle stick works in a pinch.
