The horn relay is the silver box in your second photo and the item sort of hidden by wires under it is the L side junction block. There is another junction block just like it on the right side which I believe is what is in your third photo.
The hi - lo beam wires from the dimmer switch are in the main loom and attach to the L side junction block as does the parking light feed. There is another section of loom attached on the same block which I believe in your car feeds across the front of the radiator to the right side and connects to the R junction block. With the head and parking lights connected there should be 3 wires on each terminal on the left side and two on the right.
The 3 wires from the headlight buckets are in a short approx 18" length of covered wire in which 2 wires - hi and lo beam - attaches to each of the junction blocks and the third wire which is ground attaches to one of the terminal block mounting screws. Parking lights have two wires wrapped together with one wire going to the terminal block and the other to an inline connector. I can't say for sure which terminal on the block is hi, lo, or park . That you will need to determine on your car but if you can see the colors well enough the park light terminal will have pink wires on the main and aux across the radiator loom connector and will stay connected as is. The hi and low to the headlight buckets you need to replace will be with the tan or light gray wires.
The 3 wires from the headlight buckets may be fabric covered and wrapped with vinyl wire wrap and look like the rest of the looms or they may be a black rubber covered cable which resembles a cord you would plug in the wall.
