For sale is a used SLP Line Lock for an 05-06 Mustang. I have all the parts and instructions. The wiring is in convoluted tubing to give it some protection.
I think about 3 years. I used it at the track like on like 5-6 trips there and it worked like a champ. I removed it a while back when I was in the process of selling the car. Let me know if you have any other questions.
