I just finished both intake manifold gaskets and both valve cover gaskets on my 01’ SS. In the process, i unclipped a bunch of wires and I failed to label this one. It comes off of the wiring harness that goes down between the firewall and the back of the engine and eventually all the way to the downstream o2 sensor. This particular wire comes off of the harness right behind the PS pump. It’s a single blue wire with a single prong clip. It attaches to another single (orange) wire which is clipped to the back of the PS pump. The orange wire appears to be nothing more than an 8” extension of the blue wire. The orange wire goes nowhere and is loose.

any ideas where this thing goes?

PS car runs totally fine 🤷🏻*♂️
