Another Electrical Gremlin

[96Br0nc0Guy]

96 Eddie Bauer.
replaced all three Oxygen Sensors and took off positive batt. cable to reboot ECU.

Now with all lights off, when I open either door the parking lights come on. With Driver door open, get the "Bong-Bong" lights on alarm. Pulling the Lights **** to position 1 gets parking lights still on and in position 2 headlights come on. Push **** back to off, headlights go off and parking lights stay on.

Have no dome light or door lights no matter what.
Instrument lights come on with door opening.
Could I have damaged ECU somehow?

All thoughts welcome...

ECU has no control over lighting, so you are good there.

Is there a factory or aftermarket alarm system on it? That would be my first guess. It has or had an aftermarket keyless entry or alarm system added at some point and now it is going bonkers.
