ground wires @ ecu

i am finishing off a motor install, i am hoping someone can verify the location of these ground wire mounting locations. there is a ground strap that comes around the ecu(passenger foot area) and connects to a stud on the ecu. there is also a ground wire that is on the harness with two blue connectors that did not come out with the engine harness(the one that comes out with the engine). i video taped this before i pulled out the ecu but can't see were this second ground strap mounted. sorry about the war and peace length question, any help would be greatly appreciated. thanks craig

It conects to the stud if you want to or 1 of the 2 bottom 10mm bolts for the ecu. If it is the connetor I am think of. A pic would be nice.

Yeah, this is the extra ground that belongs to the harness they put in for the fan upgrade. It plugs into the regular harness at the blue and white connectors, and there is a ground wire as well. Stock, the ground is placed on the stud that faces you when looking at the ECU when it is mounted. The stud is on the top right corner.

Or just put it on the bolts on the bottom.
