There are a number of FI grounds on the body near the coil, and a few on the
engine itself. The ground strap direct connects those on the engine to the
body. I thought you were referring to the ones now on the body. They are all
important and the ground strap is a key part of the system.

All the sensors basically complete a path from the ECU to ground or really
the chassis. The readings are basically current sensitive so any voltage
drops will confuse things and cause problems. Sometimes, it is helpful to
disconnect those grounds for testing and trouble shooting. Put them all
together and enclosing them can become a technician's nightmare. Many times
I have had to cut a part these types of improvements.

BTW- The actual current or electron flow outside of the battery is from - to
+. This makes the chassis the source. "Conventional" current flow is what we
are taught to help with the concepts. That is why a number of cars years ago
where + ground.

> You want to keep all those ground wires on the body, not the engine.
hmm  that would change how vw had it I mean there are 2 hex bolts on the
left top of the block
there are those 6 grounds from the wire harness go to thher
1 has that braid stap going to the body
Are you sugesting we dont ground wire haress wires to the block but extend
em & ground them to the body ??
