Without a manual you are spinning your wheels. There are 13 ground
points, 3 on the engine, 1 each on the frame rails under the
headlights, 4 on the doors, (1 each front and rear of the door, some
inside the cabin), 1 up behind each of the 4 wheels. Those are general
locations and may require you to remove items to access them.

From what your are describing I doubt it is a ground and is maybe the
ABS unit. It is ether faulty or the connections were damaged when it
was installed, but who knows when you have no manual to trouble shoot
it properly. Without one it is like trying to hit a curve ball while
standing on third base rather than home plate.

Try this guy if all else fails, some of the ABS units had problems
that may need updated. www.ABSFixer.com His ABS upgrade and guarantee
can make your problems go away as long as you own the car.
