My 84 has a dummy light cluster and I’m looking into swapping for a gauge cluster. Is it a direct swap or what is needed to make it happen? Also what years do I need to get a cluster out of?

you should just be able to buy a replacement gauge that will fit where the light is. But you will have to change the oil sensor sending unit I believe.

I just did this on my 86 K5.

Instrument cluster swap from Idiot lights to full gauges K5 K10 K20 K30 C10 C20 C30

Here's a quick write up while this is still fresh in my mind. I picked up a 1986 K5 Blazer Custom Deluxe that had the basic cluster with only Speedometer, Large Fuel Gauge and 4 idiot lights for Battery, Oil, Temperature, Brake. I picked up another cluster at the junkyard. It was a 80s gauge...

You need to get another complete gauge cluster. The idiot light cluster isn’t setup for the gauges and you would have to do even more work by wiring each gauge instead of using the cluster printed circuit board.
