hey guys quick question I am doing a custom dash and have the old dash out of my 68 but I tried to use my turn signals and they dont work Im wondering if they have to be plugged into the harness for the gauges to work or if I have something hooked up wrong?

The sockets have to be grounded as the OE dash was grounded by a separate wire.

So as long as when I put the new dash and gauges in they are grounded like they should be then it will be fine?

I would think so.
