this is true, I had to 1/2 wire the 02, and the 03. I just ran a new wire, and stayed away from instaling 1 in the fuse box. when my 89 was new, the small piece of wireing harness to complete the job was in the glove box, so you probably can get it from ford for some $$$$$. probably costs them about .05 too make tho.
