Need to clean all the engine grounds on a 1987 4x4 2.9 manual trans.But I don't know where they are. Does anyone have a diagram or any help would be nice.Thanks in advance

all you have to do is look all over the engine for wires that bolt straight from the engine to the body/frame

there should be one on the back of the intake manifold, one of the front of the engine, maybe one on a valve cover
