So if I buy the harness , I just remove light housings, replace, add harness "adapter", adjust, and I'm done?!?! Or is it not that simple?!
Okay forget the harness for one second step away from the harness these headlights replace your stock lights with absolutely no modification, nothing, just unscrew the bezel (four screws) that holds your old sealed beams in unplug them, and plug in the new H4 housings with the bulbs installed, and screw the bezel back in which secures the new housings just like the old sealed beam. They fit and work 100% plug and play. If you're careful and have a skinny philips head you don't even have to take off the plastic trim piece (although I highly recomend it)
Now back to the harness: if you want you can upgrade the harness for even more upgrade in light output. But it's not necessary you'll see a HUGE improvement just from the new bulbs and housings. But an upgraded harness will give a nice boost because the stock wiring is undersized and doesn't carry optimal voltage due to electrical resistence. It is more involved than just pluging it in, there's wire splicing and cutting, but it's a NOT a hard mod by any definition... it's a 1 on our Intermediate difficulty scale heheh
You can also throw away the generic bulbs that come with the housings and replace them with more expensive "Ultra High Efficiency" H4 bulbs stick them in the housings. And you'll get some more "upgrade" the ones that come with the housings are still pretty good way better than what you have on their now.
