Ok, I moved and extended the harness plugs that enter from the passenger side wheel well into the engine bay. This includes ASCD stuff, some big plug, and whatnot. The car is an automatic, and I can't find where this last plug goes into. I've checked all extensions of the main harness around the site, and im fairly certain it plugged in somewhere.
If anyone has any insight or can check their car for me, let me know. Thanks
Edit
a little more information, its part of the chassis harness not the engine harness, the one that controls headlights and whatnot, extends around engine bay etc.
