i am having guage issues in my monte carlo. i know it is a wiring issue. im thinking i have bad grounds or the circuit behind the cluster may have a break in it. but either way im looking for a proper wiring diagram. i have a haynes manual and its not the same as the factory manual. i was thinking maybe someone with all data could check it for me? or maybe someone has a factory manual with this info. any help on this issue would be fantastic -Alec
