That connector goes to the speedo side as the little DOPS circuit board lives inside the speedo housing for no particular reason. He sent me photos and he has an 85 cluster. The rare 84 tach cluster has a smaller foil without any provision for the future DOPS. The 85 foil has the extra DOPS branch you mentioned but the connector isn't installed on it and there is an extra resistor mounted elsewhere on the foil to bypass the missing DOPS. 86+ has the DOPS connector installed and is missing the bypass resistor, with an empty spot where it could be.

That only came on 86+ clusters. > > |
