The easiest way to align ur beam is to oark 20 feet from a wall. And just adjust that it center. And makes a lil box.
Thats wat I did.
Oh ya did u upgrade ur bulbs to phillips d2s?
If u didnt I would recommdend them. It is alot brighter than the morimoto bulbs.
And the phillips changes color when ur truck bounces.
from white to blue.
I upgraded mine after morimot bulbs burned out on me in 1month.
what are the harness i dont understand the different options
The harness. Is the size of ur stock bulb wires.
Which wil be H4. When u pick the harness.
So it makes it plug n play with the retro kit.
