HELP!!!!!!!!! This is my first post. I just bought a BOSS 5.4 2003. It is a 2 door F150 modified by LA West Co. It has an Alpine CVA-1004 XM radio, with a Boss DVD player. I just purchased the Alpine GPS NVE-N852A. I have installed it. and so far I love it. I have one problem. It has a speed sensor wire, that I have no idea where to connect it. I have been to two Alpine and two Ford dealers. and they say that they do not know where it goes. As it is my eta does not work. One of the Ford dealers did give me the a picture of a 2002 computer, which does show the speed sensor wire leaving the computer, but this does not work on mine I guess that the 2003 is different. Do any of you possibly have a picture of the 2003, or can you help me? I am realy a dummy at this sort of thing. The instructions say that if you cannot find it, hook up an oscillosope, and probe each wire at 60 miles per until you get a certain reading. the problem is that where my wires are, is behind the battery box. They tell you to be sure to keep you eyes on the road. LOL. If anyone can help me I would appreciate it. Thanks Jimmy

 

the 2003 and 2002 are the same.

 

Thank You. Jimmy
