Wiring gauges in a 79 k10

[Jon Cotton]

Hi everyone new to the forum. I have a 79 k10 and have taken the dash apart and was planning on getting all new gauges like I had done with my last truck(74 stepside). But it looks like this cluster is different on the back side where the circuit board is. There is not the usual 3 prong clips to attach the gauges in the back only twist lock holes for the bulbs? How do these gauges wire up?

this is the view of the back of my cluster. As you can see the 4 gauge pods dont have the locking tabs for gauges in them??

That looks like an idiot light cluster.

I was thinking maybe the sockets lock right into the back of the gauge through the bezel?
