Do you happen to know exactly where the ground closest to the ecm and motor mount
Goes. I have one grounded through one of the studs on the ecm. That same ground is connected to another about 4" away. I have it on the motor mount! Does that seem correct? Thanks

that wire goes from the stud on the ecm, to the stud on the bracket thats attached to the block, then to the harness.

as long as you are metal to metal and making good contact it should be all the same.
