Here is my story. I have alarm instalation workshop in east Europe. Recently I bought one F150 1985 5,0 with Fuel injection. As a professional I had interest to instal Italian LASERLINE alarm on that truck not for the reason it can be stolen, but just for fun. It's quite unusal vehicle for my country. No matter what European car was taking 6 hours to do the job, but F150 was something else. I have not seen so many negative pulse wires and so few positive... but surprise came later when job was done Only one wire pin was effective for immobilisation, but it looks that you can cut 99% of the wires and engine still is running
