First, under cowl heater parts, then complete dashboard.
Everything else is pretty logical but you want as much room as possible to do those two.
Under cowl cannot be done right with tank in place.
Dash cannot be done right with windshield in place.

Dash can be done perfectly with the windshield in. Fresh air vents first (and side vent pieces in the cowl area if your car is '73 on), no fresh air cables. Leave those attached to the controls that will get installed into the dash face. Then put the dash in. The dash should have the following done. The upper vinyl in place, the upper dash pad, the ashtray, the glove box door and its associated parts (the box itself, the lock, the springs for the glove box door). Get the dash so that the four studs that are on the dash are protruding into the cowl area. You don't have to install the nuts yet.
Then install the cables to the fresh air boxes. The grommet for the cables is visible where the gauge cluster would be and has three holes for the three cables.
Now install wiper mechanism inside the cowl area. The rubber stud (available from 914Rubber.com) attaches to the wiper mechanism and protrudes through a hole in the dash near the radio opening.
After wiper mechanism I'd tackle the steering column. Put the rod with the two universal joints on the steering shaft that protrudes from the firewall on first. Make sure to pass it through the bracket that is under the dash first. Then the column with key and turn signal and wiper stalk goes in. Run the windshield washer hoses from the wiper stalk through the grommet in the cowl (this one has two holes for the two wiper hoses) and run them to their respective places. Those places are the wiper nozzles that protrude through the upper part of the cowl (this line should have a tee in it) and the other to the wiper bottle (passenger side, cowl area). Now is also a good time to run the radio antenna if you have one. There is a clear plastic grommet on the inside of the cowl area, on the inner drivers side fender (where the antenna was supposed to be installed but since each dealer performed the install, some put them on the passenger side, even though there is no grommet to the fender area on that side). Likewise, there is a similar clear plastic grommet on the firewall just behind where the radio will be inserted in the dash.
Now hook up as much electrical as you can. Hazard, light, fog lights if equipped, lighter and lights to the fresh air controls.
Now attach the four nuts inside the cowl area that hold the dash in place.
Now attach the gauges. Just make sure you already have the speedo cable run up to the area. I find it easiest to offer up the gauge bezel and pull the wires through their respective holes for gas gauge, speedo and tach. Hook them up (make sure the rubber bezels are already on the gauge!) and press them into he bezel.
Now steering wheel and horn wires. Wires for ignition and turn signals/wipers can be done now too. You can also now tighten all the steering colum bolts. Five if I remember correctly. Four to hold it to the dash and one that holds the tw pieces of the column together.
Now the bolt under the dash, and the four screws on the sides of the dash (two on each side, visible when the door is opened all the way).
Now knee pad. Then vents. Then center console if equipped.
In cowl area fit the fresh air box. I don't know where you are with brakes. But if the MC isn't installed I'd do it now, along with the lines and reservoir.
After this A-pillar covers, etc.
Glass in last helps because you're not having to jump in and out of the car constantly to run from the dash then to the cowl area and back. If it's out you can just reach over to do some of this work from the passenger compartment. But if it's already in no problems. After all this put a nice new windshield to dash rubber piece on (also at 914Rubber!).
