So I just had a new engine installed last week. The shop apparently didnt tighten down the purple ignition wire, as its not attached. Theres also a very thin gray wire the same length, not sure if its critical. I got a new Procomp starter, and am unsure of where the 2 wires go. The car is low, so I cant get under it without a lift. I can get to the starter by the side of the engine, but cant really see whats happening down there. Any ideas?

 

See attached Images. one of the purple wire (Has an eyelet that im holding) one of the gray wire that im unsure about, and the third is a peneral pic of what can be seen, like the orange and red wires.

 

On my car, my knock sensor has a white wire, which is closer to gray due to age and grime. My knock sensor is also by my starter.
