NEED HELP ASAP Wire Harness Question

I was wondering if someone could tell me where these two wires go, need help ASAP, trying to get car running today.

There are two sensors that plug into the Supercharger. From there, they go down to where they meet the wire harness underneath. Right where they meet, there are two wires coming out (both look like grounds) however 1 is hot and 1 is a ground. Where do they go?

It appears that everything is connected correctly however there seems to be nothing within reach where these can connect.

I need help ASAP, I need to bring the car to GM tonight for an inspection and I can't get her running.

Can anyone please take a look and trace those 2 wires down?

need a pic. did you take the engine out and now put it back in?

I'm gonna take a wild guess and say the hot goes to the starter top bolt, and the ground probably either connects to the trans or under the driver's headlight.

Turns out they are both grounds but for some reason it was reading as a hot wire on our power tester. All is good now though.

i have a feeling one of them is your knock sensor....as the knock sensor and the ground are positioned right next to each other

My friend PJ took apart his wiring harness that he has no use for and followed the wires to find they were in fact a ground. I didnt want to short something out by grounding them if they werent supposed to be.

I was just really confused at why it would be lighting up our power tester. But grounding it is what it needed. Car started up fine with them grounded.
