69 Cuda wiring problem

I’m doing a basic stock restoration on my 69 Cuda, and am having some electrical issues I’m unsure of.
I did the Mad Max (or whatever) modification that bypasses the bulkhead connectors and disconnects the amp gauge in the dash. I used the recommended wire gauge, the two fusible links, and soldered crimp connections, etc.

The problem I’m having is that after reinstalling the dash, I’m getting a small charge through the circuit that the dash lights/console light are using, even when the ignition and light switch are off. When I turn the light switch on, they all get brighter per normal, but remain partially on when switched off.
A couple things to note is that I haven’t yet installed headlights, backup lights or tail lights, so my thought was it could be a ground issue there? Also I’m using LED bulbs in the dash, for what it’s worth.

Any ideas where to start troubleshooting? I really appreciate the help.

Thanks, Doug
