converting to the full instrument cluster option U-14 from the speedo/giant gas guage cluster. needs to have an extra wire or two to run the small clock and the "voltmeter".
the problem here is that i discovered my U-14 does NOT have a voltmeter, which would be wired as shown, but in FACT has a frikken AMMETER!! so i got a voltmeter off ebay. spozed to be safer. easier to hook up with wires shown in first pic as well. i had an ammeter, but it turns out it didnt work. voltmeters replaced ammeters as more reliable in about '74 anyway.
there is quite a bit of material you have to read to do this properly, as the plug in connector has to have 4 or 5 wires removed and re-connected in different holes, as well as having to add a wire from the connector to the distributor for the tach. go to www.nastyZ28.com and click Restoration articles, then Interiors, then U-14 instrument cluster swap. there are pictures and a detailed explanation of what goes where. also you have to deal with undoing the bottom dash parts under the steering column and drop the column about a 1/2" to get the cluster out.
NOTE: TACH DID NOT WORK AT FIRST. NOTICE ON LEFT CENTER-BACK OF TACH- ON THIRD PICTURE, THERE IS A HOLE IN THE CIRCUIT CARD! I HAVE PUT A BOLT AND NUT THERE. THIS IS THE GROUND FOR THE TACH. AS THE HOUSING IS PLASTIC, LIGHTS IN THE TACH WILL NOT GROUND IT. I BELIEVE I HAVE FIXED THE TACH PROBLEM.
