I need some info. If anyone has a manual, could you look up the pinouts for the base cluster (speedo, fuel, temp) and the pinouts for the full analog cluster (speedo, tach, oil psi, temp, etc). I wanting to upgrade to the full analog cluster, and I need this info to do it. Thanks!!

As you can see, there's only like 4 differences...the only pins that are different are:

 

C3

D2

D7

D13

 

Now for C3, it looks the same but different...one says "INPUT" and one says "INDICATOR"??

I think I understand C3. For the base cluster that is the input for the idiot oil light, on the full cluster its the input for the oil psi gauge. I already knew I would have to get a new oil sender, so the oil psi gauge would work. And for D2 and D13, I dont have HUD, so I dont even need these wires b/c they are outputs from the cluster (if I read that right).
