I have a 1989 Camaro that I am rebuilding. I did buy a set of 4 of the sealed beam conversion lights. I have none of my old bulbs to test the system. Here is what happens,

Turn on headlights, Low Beam. All 4 lights come on, outside very bright, insides very dim.
High beam. This reverses. Low goes very dim. Is there a difference on these bulbs, as to my originals?

This headlight harness did work correctly in my car when I had it running before. The headlight switch in the car has been changed, and I am not sure of it working correctly.

If there is a adapter harness I need to make this work, Has anyone done it at home, rather then buying one? I have relays etc laying around. Thank you in advance for your help. I did search, but could not find this exact problem.

 

Think I found a thread that shows a adapter to flip flop the ground and low beam. I should have looked a little harder before posting.
