I saw a box that looks kind of like an ECM inback of the glove box of my 84.. unlike the 87, it only has 1 set of wires connected to it, not two. What is this for? Is it for the 700 tranny? is it something for the carb? <A target="_blank" HREF=http://billybob.coloradok5.com>http://billybob.coloradok5.com</A> If it ain't leaking oil, it ain't my truck!
