i have a 1984 chevy camaro z28 HO. I'm trying to get my temp gauge to work. I know that the gauge itself and the sender are good so it seems to be in the wiring. I have a c100 bulkhead connector diagram and by going by that it says that the sender wire is light green and is in location F7. I looked at my connector and i do not have any wire in the F7 cavity. Do i have the right diagram or is it wired through the computer. I have since disconnected the ecm and it seems that ever since it hasen't worked thanks for any help
