Which headlight harness?
I've done some searching and seen bronco graveyard also has a heavy duty headlight harness as well as lmc. I've read some mixed reviews on the lmc but mostly good. Have really heard how people like the bronco graveyards. Didn't know if there were any other options for these things? It's next on my to do list.

Make your own. You will need fuses, two Bosch relays, some heavier (10 or 12 gauge) wire)wire. In general - the three-post sealed beams use one post for the low beams and the other post for highs, the third is your ground. You will use the current headlight circuit to trigger the relays (which requires less power) and set up a new circuit using heavy duty wire to route battery power direct to the headlights. All the load is on the new heavier wire, so you reduce the load on the old headlight harness and make a more efficient connection to the headlights. There are multiple posts about how to do this, do a search and you should find theme easily. The total time needed is probably about 2 hours if your work slowly. Since your headlights will be powered by a very short harness using heavier wire instead of using the older high-resistance circuit that goes from battery to switch to dimmer and back up to lights (all potential failure or bad connection points) you will probably notice a noticeable brightening of your headlights, too.
