Dash cluster connection problem

1969 C10 step side. Converted dash cluster from 3 gauge to 7 gauge window.

To start with: Everything worked with the 3 gauge cluster.

I have re-positioned the input cable connections for the 7 gauge cluster.

Before installing, all lights and gauges were tested and working with the brand new circuit cluster.

Now these don't work...glove box light, front side lights, cluster and factory gauge lights, gas gauge level, dimmer for cluster and gauge lights, dome light

These work...headlamps, high beam, rear side lights, directionals, stop/tail, heater, radio, wipers/washer.

To clarify, I have not used the factory temp, or ammeter connections on the new circuit cluster connections but have put tape on them so they don't short somewhere. I have separately wired the ammeter, oil pressure, water temp, and tachometer, which all work.

I have separately wired the (Autometer) tach light, temp light, oil pressure light, and amp light (parallel) and connected them to the fuse box cluster tab, and separately wired their grounds to a new bolt connection on the metal dash. So, now these are independent of the cluster circuit and work.

The first question is: Could my problem be related to no connection on the circuit cluster to the taped tabs intended for the factory gauges (temp and amp). Should those tabs be shorted across as though they had an instrument? Am I interfering with an incomplete circuit?
