1JZ ground wire locations

[ronnie4]

Guys where should I put ground wires on my 1JZ

One from the side of the block to the battery?
One form the valve cover to firewall?
One form side of the block to the firewall?

Anywhere else?

I put one from my first coilpack to a ground, one from the block to a ground and one from the head to a ground and also one at my battery. I don't know if this is right, but it works for me.

Did you just splice into the ground coil pack wire?
