3) power steering light is on
4) TPMS light is on
5) from the drive seat I can only control driver window can not control other windows. The other window controls work from their respective door panels
6) Multi terrain select is not available
7) Odomotor, speedometer, and tachometer don't work.
8) ambient temperature sensor does not work
9) Gear of transmission display does not work on the dashboard
10) slip light indicator is on.
11) remote key entry does not work
12) a lot of the fuses will not light up when I try to test them (like Half of the fuse box).
13) car has a rough start and idle. seems like it wants to die on cold starts.
I appreciate your help. I am guessing its the ECU or the wiring. Whats throwing me off is my diagnostic computer can not even connect to give me codes (it turns on when connected to the obd2 but can't read the car). When I opened up the panel I noticed the alarm was disconnected so I am guessing the car was stolen. Any help in diagnosing a wire problem or eco problem would be of help.
Thanks

Ouch is right. First, as Jivewalker said, make it the seller's problem if at all possible. If you bought it as-is, then you may be done there.
If you're stuck with it, I'm wondering if you could pull the fuses for all the things that aren't essential to running (lights, AC, ABS, etc.) and see if anything changes as far as the dash lights and rough engine. You could then re-introduce a fuse at a time (after making sure it's good) and look for changes. Maybe someone maliciously slashed or ripped a wire bundle, or did some other damage, creating opens and/or shorts. Also, not sure what you mean by fuses not lighting up. You're pulling them and checking with an ohmmeter?
One thing maybe - the window lock switch could be engaged or bad.
LandCruiser could be right about the ECU. Best wishes.
