Sure makes a difference when you get the full system voltage to the back side of the 
headlights.  With my '82, I did the harness first and found the light output was so much 
better, I left the existing headlights there (halogen sealed beams):

When you only see a little over 10 volts at the bulbs, you are losing about 1/2 the bulb's 
light output:
