New to the forum (but a long time Challenger's owner).
Just recently I have been having issues with the ECU, Ballast etc. I found a 5 pin EUC laying around and replaced my orange box with it. The Challenger started great! I saw that the 5 pin came with a 4 prong ballast. I didn't give it much thought until now. I'm still using the 2 prong ballast (only 2 days).
What would be a good replacement for the Orange Box?
