Head light wiring upgrade, so many choices, are they all the same??

[NASTY-LSX]

I have searched and searched and came up with many choices for a wiring relay upgrade. H4 headlights also. When i drive at nite, i might as well leave the lights off cause i still cant see the road LOLOLOLOL.

I have seen these relay harness from $29.99 to over $200.00
My question is, ARE they pretty much all the same?? some of them you have to ground each headlight pig tail individually, some you dont. I have seen some wire up differently than others. Cheap and quality looking one's..

I would love to buy a quality built 1 but not for $170.00. I assume they use bosch or equal relays with thicker gauge wire. $29.99 well you can tell they are just what they are, Cheap parts (relays)

I am not a electrical guy. I can build, fab, paint, everything but electrical. I seen some prints to build my own and dont understand the print lol.

Anyone know someone who builds these with quality parts??

My guess was to buy this

As use it as a mock up to buy better parts and wire to build my own.
Any help would be a great.. THANKS

my truck is a 1985 silverado K20 4 headlights.
