Help with cluster swap idiots to full

[Dale99]

I'm working on my dads 67 that was base model with idiots, and grabbed a cluster out of a parts truck we had.

I've found a thread from about 1.5years ago with typed pinout, plus link to one of the parts suppliers that had diagrams.

On pin 12 blk/brn, it says terminal by battery with 4amp fuse. I am assuming this is to be hot all the time?

If so, its making pin 1 hot all the time which is the trigger to the regulator correct?

Is this suppose to be that way?
