Hope folks can help.. Have an '88 wagon and seem to have a cluster problem...Only indicator lights working are OD and High Beam. Odo/Speedo not working. Can folks tell me which wire grounds the cluster? I have voltage through the fuses, and I figure its got to be one of the leads on the ) plug, but ran out of daylight.

Don't remember exactly. Its on the half moon plug not the round one. I think it the black wire. On the old clusters its the first pin nearest the spedometer. I am pretty sure it is the same on the new (electronic speedo) clusters. If you look between the clock/tack and the speedo you will see a brown jumper wire. Thats a ground wire so you can check for ground there too. Also the brown wire on the back of the clock is ground, and if you take the clock/tack off the pin on the far right is ground. Hope this helps.
