Hello~ This is a question concerning a T-100 2wd w/AT and 3.4. A work associate asked me about a problem he's having his truck (the aforementioned). I told him I didn't have the manual for his truck but it sounded like it could be electrical ie. loose/bad connection or fuse. His son just replaced the speedo cable and his overdrive and cruise quit working. I've never worked on or ever really been close to a T-100 so I don't know how the cable is routed and if somehow a connection got jostled loose. Since I have no experience w/ this truck, any help is appreciated. Thanks
