Entire Instrument Cluster Flashing - Gauges Spastic

[Seadweller]

I checked operation of the lights, and they don't react to the cluster blinking on/off, so I'm going to go with the assumption that it's not related. First click on the ignition switch the cluster lights up, and then second click on the ignition it starts the blinking routine. Oddly enough, it almost seems like it's on a blinker type of relay, the way it clicks on/off is a very distinct pattern.

The blinkers work fine, as do the hazards.

What connector should I use to test voltage to the cluster, and which pins within that connector? I'm going to order an ignition switch today, and cross my fingers that's the issue.

Thanks a bunch!! I hate when stuff doesn't work as it should.
