not sure goal;, fogs, or eliminate the Combo switch or?
keep 2 fuses in the path (red) to the new relays, so that if one path grounds out, the other still works.
preventing total blindness , driving at night, say on a moonless night, on a cliff road.
some of the older drawings are not so good (like #1 above). try this.
the relays only help the COMBO switch last longer. but with added cost and 2 more things to break.
Drawing 1:

i took the 91, and mixed to drawing into one , to form a unified, HL drawing. below
Drawing 2:

these drawings are more clear, what do you think.?
note that both fuses are HOT all time. per USA laws. (safety)
the 96 drawings are in the fsm, off my books page. for same.
one advantage of hot head lamps is if the control side shorts, the head lights still work, fail safe, if on the other hand you run , hard grounded HL , then any control failure, results in at least 1 dead
headlight, or if you parallel that control , you get 2 dead headlights.
see?
the arrangement is not by accident.
one more improvement i saw an many cars made in the 50s was a thermal circuit breaker, that opens on over load, then resets automatically, this can get you out of a jam. with dead head lights. (they reset and dim head lights are better than non.)
