Default Electrical problems on my 92 SC400

Aside form the CEL that's on that I learned to ignore, (when I read the code, there's none stored).
The O/D switch stopped working. I use it a lot to "downshift" so I really need it. On the cluster, the O/D light is partially lit all the time and when I turn it off the light goes off.
ABS light is on and I think I lost ABS
TRAC light comes on randomly.
I think I need a new ecu and abs ecu...
My after market remote quit working so the car alarm goes off everytime I manually open the car. I just fixed my side mirror because I think somebody wasnt looking where they're going and hit the mirror forward.
darn it! every time I fix something on this car, something else goes wrong.

Sound like something is grounding or it can be a bad ecu or harness .Goodluck finding the gremlin .I would first check all grounds inspect transmission/ engine harness. it that dont fix the problem replace the ecu. Whats the milage?

It has 240K+ miles and still smooth and strong. I noticed when I was checking the ECU, the carpet was damp. Its possible that moisture messed up the ecu's
