Where Are ALL the 7M-GTE Grounds?

[MA70witBoost]

Getting ready to drop my motor back in the car and i want it running good with no issues. I remembered a wire that is by the fuel rail/coil packs that is just loose. Looks like a ground to me, so it got me thinking/wondering... Anyone have a diagram/photo/pdf, etc. showing the ground points for the 7M? Thank You!

no diagram but, you have one by the back of the head that goes on the engine hook, tranny ground, main ground with battery, coil pack, i know i am missing one, just can't think of it right now...

From the ECU there are 2 sets of ground wires... with 2 wires in each set(i think) both on same eyelet....... one pair of brown and other is white and you have your coil ground... ground from bellhousing to frame by starter... and ground from transmission mount to trans bracket

coil ground needs to go to intake... not valve covers...
