Also you'll have problems putting in the factory headunit. It wont come with a wiring harness because the wiring harness would still be in the car. Judging by what the speakers look like and how their put in I'm gonna guess he cut the factory harness and attatched the wires to the new stereo with electrical tape. If this happen then you will do better getting an aftermarket radio that has the same look then the factory one. If he did it right with no cut wires then your really lucky.
