I am in the process of converting my 69 over to have console gauges. I got the harness for the console and the adapter harness and have it all installed. The gauges appear to work properly and I have power to all the console gauge lights. My question is, does each console gauge need to be individually grounded to make the lights work? There is only one additional ground wire in the new harness I have and I connected it to the front console mounting point. Should I have connected it to a gauge instead? Any replies are greatly appreciated. Thanks.
