yea when i bought my coba i noticed a bunch of loose connectors .. im thinking it was from the sai taken off the car when the vortech was put on not sure on the ground wire ..i'll have to look for ya
I'm almost sure that 2nd pic is the wire that goes to the fuse box from the alternator. I could be wrong, but I don't believe this is a ground. There's a screw in the bottom corner of your photo with a plastic cover of the power distribution box.
First plug almost looks like it hooks up the the fan module. Hard to tell though.
2nd pic there is a small black box attached to fuse box the door slides up and there should be another wire going there red one both of them should be together on that bolt.
As for 1st pic do you have a metal line right under your hand ( i dont know whats called) there should be a place to connect that.
