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

[vlow1210]

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 but they are way off (It shows me going 30mph 2700rpm in 4th gear, 25mph 3000rpm in 5th. But it really feels like I'm going 40-50 when it says I'm going 30)-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? Thanks in advance
