66 Inline Fuses
Finishing attaching the new dash harness to the back of the instrument cluster. I have read that inline fuses should be placed in the following:
Cigarette lighter (RED WIRE)
Battery Gauge (BLACK OR THE BLACK/WHITE WIRE ?)
Any other locations?

The cig lighter fused is a good idea if you want to use it for anything but for what it was designed for.

Besides the cigarette lighter and battery gauge, the rest of the stuff coming off the unfused side of the panel is covered with circuit breakers (headlight rollover, power windows, light switch). I think the feed to the ignition switch is unfused from here too. The power antenna on a 65-66 is the only other one not covered so a 15a circuit breaker or inline fuse would be good. The cigarette lighter should have its own 15a inline fuse ... I don't like fusible links ... they make a nice little fire when they go! Bill

All true, I will add:
The brown wire that goes to the radio capacitor on the back of the cluster.
The purple wire that goes from the ignition switch to the starter solenoid.
And, in the engine compartment, the 10 gauge wire that runs from the starter solenoid to the voltage regulator. ( In '67 they added fusible links at each end.)

As I mentioned before in a different thread, in 1967 they added a fusible link on both sides of the battery gauge. Why not do the same? (except with fuses, not fusible links).

I put fusible links in the 66 wiring harness per the 67 diagram. What I found is the wiring on the 66 IS NOT of the same gage as the 67 wiring, and thus the fusible link was the same gage as the wire which does very little to protect the circuit. You need to compare the two diagrams and use a fusible link approximately 2 gages less than the wire gage (e.g., 10 ga. wire - use 14 gage fusible link and 16 ga. wire - use 20 ga. fusible link).
If you are using fuses, I would recommend a slow blow fuse and select the fuse amperage to somewhat less than the maximum current capacity of the wire.
I personally don't like fuses under the hood nor any area that could become wet.
