I haven't been able to get a repair manual for my 2005 grand prix, so if anyone can help me out on this i will appreciate it.... There is, what i think is, a cable looping thru the engine compartment. It goes from the engine or tranny to the fire wall and at the midway point of the cable is what looks like a coupler, a point at which it looks like you can disconnect the two halves from each other....WHAT IS THIS?????? Is it the spedo? Is the spedo electronic and connected to the tranny with a plug or is it that cable?
P.S. is a repair manual for the 04 the same for the 05 models?!?
