Odd electrical issues: lights stay on, gauges don't work

[rps13_fastback]

I just completed an SR swap into my 92 240sx. I'm having some weird electrical problems.

1. The seat belt/parking brake/door ajar lights stay on even after I remove the key from the ignition.

2. The seat belt chime stays on even after I remove the key from the ignition.

3. The fuel and temp gauge on the cluster do not work (the temp gauge is a different story though. My coolant temp sensor isn't plugged in) But what gives for the fuel gauge?

4. My dome light doesn't work anymore

-I haven't replaced the fuel pump yet.
-I used my stock 92 cluster, didn't touch it. Tach/speedo work fine.
-Sometimes when I push the parking brake button the light will turn on/off.
-My radio is not connected (I took it off cause the car is sitting outside so I don't want theives seeing it). When I touch the wiring sometimes the parking brake lights will go on/off.

Anyone know what it could be?
