I have a 1984 Firebird 305 5L. and I bought theses lights: Halogen Semi Sealed H4 Crystal Clear Glass Headlights (60/55W). The website says that they are plug and play but they are dim. I have been searching all over and some threads say "get a relay harness" and others say "change the head light connector pins 1 over clockwise, because the H4 light bulbs are wired differently". I am so confused and not sure what is the right approach.

Please help me out.

Thank you!!

Maybe you need the harness that is plug & go.

either will work. the relay harness method will make them brighter though. The plug and play harness is just a harness that already has the pins swapped over. i built my harness in a few hours if thats any consolation.

Will the plug and go make them a bit brighter too? Right now they look very dim. I have not done any pin changes to it.

Compared to what you have yes. Your lights are not operating properly, swapping the pin or buying the harness will yield the same result. If you do a relay harness you're putting more power to the lights which will make them brighter than normal operation

Thank you BluFBd and t-top havoc for helping out. Much appreciated!

Perhaps they need the balast component as well?
I just purchased a kit with the wiring etc, and they coem with two powerpack looking things that I'm assuming convert and power the lights.
