I took some pictures, but I need to figure out what size and resolution the site requires, and I think it will help. I have found other issues in this process. The connector with the 3 wires, LT GRN, TAN, and DK GRN, are on a 9-pin connector utilizing the middle 3 pins and it directly fits a seperate connector on the back of oem stereo. And it will not reach the instrument cluster.
There does seem to be a 3rd connector on the cluster for which there is no connector but it is probably a factory test connector, between the 2 functional connectors.
When I looked at the back of the fuse panel in the engine compartment I found 3 double splices. It appears that a small PNK is linked back to a small PNK. A GRN/WHT is linked back to a GRN/WHT, but a small BLK/WHT is linked back to a larger solid BLK wire on the block. I have clear pictures of this and will post shortly, after I figure out what to do.
