Just bout a 93 325is 5-speed w/140xxx miles. Currently doing maintaince work. Just did an oil change using Castrol GTX 20w-50. Replace all pads and front brake wear sensor. Still need to replace serpentine belts, transmission fluid, diff fluid, recharge a/c replace leaking valve cover gasket, fuel filter, spark plugs, and worst the flex plate. (Any recommendations on the trans and diff fluids?)
Now my electric problems.
Battery doesnt illuminate-replaced bulb
ABS light stays lit
SRS light constantly blinks
Check engine light on
Seatbelt light doesnt illuminate-replaced bulb
When you start the car check coolant pops up then disappears, same on turning the car off.
Need to figure out how to delete factory amp/wires.
Driver window has to be pressed million times to finally be down all the way same for bringing it up
Window doesnt crack open on open and closing door
Dome lights doesnt light when driverside door open
*Can anyone help on these pics?

Purple/green and Brown wire located behind message thingy. same wire bundle for the message thingy.

These to big plugs are located behind the glove box.

Wire was hanging on the passager side by the foglamp. Missing plug. Green and Green/black I was thinking it belongs on the brake vent piping?
