On a Dodge Neon how many ground wires are there on the engine and where are they?

There are three ground wires to the engine. One goes from the Strut Tower to the back of the Cylider head left hand side (front) of the engine. Another goes from the Strut tower to the top of the engine mount. The third one is on the back of the head on the right hand side. This ground has a square black transistor on it and grounds the ignition system.
