I have spent days trying to fix this car.
If I apply brake pedal the engine cuts off. If I remove the brake fuse
the engine does not stall with the brake pedal applied.

I changed the alternator last night and no better.

The left tail light I disconnected the whole assembly. When I do this
the cars RPM start to go down and the engine shuts off. If I plug in
the harness I can start the car again.
One other crazy thing, when I disconnect the rear tail light harness
the ABS will light up n the dash.

What else can I do to pinpoint the problem?
Thanks

Check battery and connections. Check all grounds. Check fuses. Take it to
someone who understands how to troubleshoot electrical problems.

It is too easy to take it to a shop. I like to figure out problems and
always accept advice,
A shop is a great idea. But it is my last resort.
I pay more for auto insurance than the 3 beautiful cars I have.
Saturn 2 yrs ago 100 k miles 650 dollars have driven it all over
Geo metro 150 k miles 675 dollars have had for 4 wonderful yrs now
Needed exh manifold MIDAS qute for all exhaust 1200 dollars Manifolt
and complete exh less than 300 dollars

BMW 325 IS 155 K miles runs great, Free. Rear wheel drive not so
good in ice and snow
will keep another 15 years not a spec of rust.

Then spend the money for the real shop manual, get out the electrical
diagram, and see how the relevant circuit could be connected to the
transmission control or the engine control. Or if there is a shared
ground.

Without the schematic you are wasting your time swapping things at
random. Get the schematic.

Agreed, it's a bad ground somewhere -- impossible to troubleshoot
without a shop manual.

Clean all grounds: engine, lights, alt, battery, etc.
