How does the Rallye Dash Tach hookup?

How about why'n e'll don't you tell us what it is that you are working on, and look at the correct year?

Look at the BOTTOM connections in your box. There are three groups

One fuse only, on the left, has a tan on the bottom, orange on top. THIS IS the "instrument" (cluster lamps) fuse

The second two to the right are fed by one buss (on the bottom.) These are the "hot" buss, not going through the key

The last three on the right, are fed by a buss on the bottom. These three are fed "through the key" IE they are hot in either "run" or "accessory."

So if you haven't figured this yet, the power feeds in your photo all come in on the bottom side of the box, and the loads are fed off the top connections.
