How is the VR grounded?

You say you have "no chassis grounds" but this is misleading, because these are a unibody. "There is no" chassis." Since SOMETHING in the car has to be grounded to the body, what do you have from engine to body?
wow... if there is anything that takes a ground...it has a wire grounded to the battery/cable. i do not rely on body/chassis grounds. but i do have the body grounded with new ground straps this car is over grounded.... i did not want to take any chances with the new electronics
