And just add a 4 amp inline fuse on this new line correct?
I am not 100% sure how this is routed to the alternator. I know it should come out at the bulk head and be part of the light harness. The fuse is near the voltage regulator on the firewall. Yes you will need the 4 amp fuse in line.

Yes, that wire does run through the bulkhead connector and was originally part of the front light harness. There is a factory splice inside the harness where several large red wires join together. The 4A fuse for this leg of the battery gauge (ammeter) wiring should hook to that splice. The wires going to the alternator can stay the same.
Here is a diagram borrowed from another post on this site (the splice is circled).

Yes, from the factory it is about 3 or 4 inches of pig tail with a short style glass 4 amp fuse. From my understanding, you will need 4 amp in line fuse on both the #1 and #12 wires. Anything different will cause the gauge not to work correctly

I agree. Using 4A fuses on the battery / alternator ends of the #1 & #12 wires will protect those wires in the event one of them is ever shorted to ground. The fuses will also protect the wires and the meter movement from trying to pass too much current should the "shunt" wire ever develop an open circuit due to a bad connection.

They are called terminals but not sure the actual technical name for them for this applicatiopn. You can see in my photos on this thread how to remove them from the connector. Both non gauge (warning light) clusters and full gauge clusters share the same 12 pin connector but the terminals are located in different places. I have never been able to source new ones so if you need extras, you will have to get them from a junk harness.

I believe they are called "bow" type terminals. In this case, I think a person could salvage the terminals off the brown (gen light) and dark blue (oil light) wires since those wires are no longer used with the gauge cluster.
And like Ewr101 said, Classic Industries does sell a kit that includes new terminals along with the plastic connector shell -->
