Luv Da Lex

So when I had me tein ss on somehow my wheel well plastic guard got ripped off the car. Then the coilovers itself decided to unlock itself and it went to the lowest position possible. This cause my car to rub against the expose wiring loom and now its a headache and a half.

I talked to aliga about getting a harness to replace the one that is totally messed up now. I have no signal, no windshield wipers, no climate controls and my side mirrors can't be adjusted.

Aliga told me that the wiring harness that goes under the left fender from the fusebox under the hood to inside the car is plug and play. He said its pretty long but not that hard to replace. I looked and I can't see that it is plug and play for the fuse box and the harness disappears into the firewall.

My question is:
Can anyone confirm that it is plug and play?
Where does it end up inside the car?
Anyone else have this problem and fixed it already?

I appriciate any suggestion. Thanks
