Urgent Help: Look at your wiring harness please!!!

Hello,

I just replaced the engine in my Aveo and I need help identifying where these two wires go... There are 5 small wires in each set and they have an eye for a bolt to go through each one.

They both come out of the main harness coming out of the fuse box.

Here are some pics. Please take a minute to look through your engine bay and try to identify where they are bolted into.

Thanks in advance!!!

These look like they are ground wires and should be grounded to engine.

Why do they have 12V if they r ground wires??

They were grounds... Bolt up to the long stud on intake manifold... Anyways AVeo is alive, with one bolt in exh mani, and intake not hooked up yet totally.. 11pm, my neighbours will kill me..

Thanks for help!
