90 corrolla Ground points

[lpbaca]

Can anyone tell me where the grounding points for the whole electrical system are? I have a ground issue and need to locate them.

on factory there's only a few......

from the battery to the trans and to the chasis.

on the passenger side there's one on the backside of the engine to the strut tower

in the main harness the ecu ground is bolted to the intake manifold
