Yes, without saying what car is being worked on, Jaybu02 is not making it easy to help. I took an extra minute to see what the car is and it appears to be a 2003 base model w/manual transmission.



With that info, the wring harness from a 2003 being installed makes sense. The problem is most likely an error or missed connection in how it was installed.

Troubleshoot.
Trace the power from the source to where it is supposed to go.
Check continuity of grounds.
...stuff like that.
