Default Guys plz help im freakin out windows and other dont work

Hey guys ok My 95 ls400 i took off the door panel to do some work on the handle.
i snagged a body module from the junkyard month ago . Just because i thought it would be good to replace the door computer. As i was pulling off the harness i noticed there was a brown and white wire spliced into the middle harness( computer harness). Does anybody know wat it does? Anyway i disconnected that. Put the new door computer 1 in plugged the door window switch in tryed rollin down windows nothing .tryed sunroof nothig tryed to tilt the steering wheel.nothing. tryed movin the mirrors nothing. So i thought maybe those wires were somethin spliced them.back i have no clue wat they do. Or where they go.. still nothing i plugged in 3 difd wimdow switches nothing!! Put orignal computter back on nothing.next i thought surely i blew a fuse. For one thing theres no power window fuse / sunroof fuse. I did find door lock blew twice. Any ways im out of options. Plz plz help. So i can get this done thnx i know someone got an answeer!!!

If it was working before you took off the door panel then at least you know where to look for the problem. Do you have a meter for measuring power? That would be helpful.
If you're blowing fuses then you've got something shorting out and causing the problem. And you may have multiple problems. You're just going to have to retrace your actions and see where you might have messed something up. Sorry, but no easy answer here, other than look at what you touched/disassembled.

Disconnect the battery for a few minutes, reconnect, and then try again.

Did you disconnect the battery terminal and wait some time to discharge electrons before you start the job?
Doing any computer related job needs to disconnect it. Most of computers are getting +B 12V from the battery even when the key is not inserted. I worry about the MPX body computer is damaged since the sunroof doesn't work other than doors.

So you didn't disconnect it. The next important step is to read the error code of the MPX Body System short-circuiting "Tc" and "E1"at the TDCL or the Diag Connector. 8 different codes 11-15, 21-22, 31 and 41 are used for this diagnosis. I hope it's not 14 or 15. These 2 means that the MPX bus doesn't swing as it should act.

I dont understand why there isnt a easy fuse. To just put back in.
i was workin under the dash. And carefully went through all the wires. To see what previous owner installed. I put all the wires back exactly the way they went.
turned on car. To see if windows work now the ac panel was flashing defrost. But no ac was comin on. I said ok duh. I blew a fuse. Theres no fuse no anywhere no numbers comin on ot anything dmanitttt.
where is this fuse there has to be one.now i really cant drive the car its 104 here no ac and windows dont rol down il die!! Lol

Ouch! One of the pitfalls with a previous owner that's hacked into the wiring system. May be worthwhile if you haven't to sign up for Toyota's TIS services to get manuals and wiring diagrams.
