I am converting my 69 no console gauges no tach to have them. I bought the console gauge harness, but was wondering what else I need. Do I need to buy a complete under dash harness for a console gauge/tach car to connect everything up or ???

You will also need the extension conversion harness that plugs into the console harness. It comes with the instructions on how to connect to the fuse panel. You will also need the tach harness(no biggie).
