Yes it has quite a few Ground wires.

They are brown bolted to a cam shaft bearing cap when it left the factory.

Here is a link that tells you what each pin for the ECU is for. The ones that start with an "E" are the grounds. They are usually brown, or brown with a black stripe.

Go to page EG2-184 on this link...
