1967 - 1969 barracuda Instrument Cluster Lights Out

8 bulbs total, 4 illumination, 4 indicaters. All except the park brake indicator use the same chassis ground path which is parts and hardware.
A perminant dedicated ground wire is strongly recommended.
Illumination power is orange wires, 1 in the round connector, 1 in the smaller inline connector. There is a splice under the harness wrap where these 2 wires are joined.
Check power at both orange wires. Look closely at every bulb socket. The tiny ears that hold them in place tend to snap off. I have the NAPA part number for those here somewhere.
8 new sockets and 8 new bulbs will be pricey but again, strongly recommended. The more you feck around with the panel the more change of breaking something.
The printed circuit boards are too simple. If you can get the rabbit to the Trix on the back if the cereal box you can read these boards. Set the panel on a work bench, get a couple of jumper wires with aligator clips and test everything.
My customers take their panel out and put it back once and done, for a very long time. The do it yourselfers do it repeatedly. Good luck with yours.
