Car- 93' Nissan 240sx with an S14 swap (also an auto to manual swap I believe)

I came to my car one day after it perfectly running and I turned the key and got nothing. No lights, no power. First I thought it was the battery, so I tried to jump the car and that didn't work. I then got a new battery and that also did nothing. I looked under the car and found a couple of cut wires going to a sensor that I have not been able to identify. It is the sensor right before the speed sensor towards the back of the transmission (right before the rear transmission mount when looking at the transmission on the car). I have heard that this sensor is not necessary an that you can run without it. I then replaced the transmission wiring harness in hopes of getting power back, but I still have nothing. While I was taking the car apart I also replaced the starter (and starter solenoid). When I was reconnecting the battery cables, they sparked indicating that some sort of electrical current was flowing, but as I said, I still have no lights or power. It has been really hard to identify what sensors are unplugged and are needed, and which ones are vital, because some kid did the swap on this car and left a lot of things hanging. I have truly tried everything and the problem is beyond the mechanical knowledge of my friends and I. If you have any ideas please let me know and I'd be happy to provide pictures/videos for reference.

Check fuses
Did you by any chance put the battery cable on wrong?

Ill check to make sure, but I grounded the negative battery cable on the intake manifold and in the battery tray (the same way it was when I took it off) and grounded the positive cable on the starter, as it was when I took it off. I gave all my fuses a good look over and they seem to be fine. Im gonna head to work on my car around 4 so ill give the battery cables another look, but to be honest I do not think they are incorrectly hooked up.

Volt meter and follow the voltage flow through the circuits. Make sure you have power at the key solenoid for on and start.

I really meant for a split second, because that's enough to blow fuses.

Is a volt meter a multimeter? And could you explain the process a bit more? I'm a novice when it comes to electrics

That's a pretty simple explanation.
