This a great thead thanks to all those who have contributed. Purchased a 15 Chevy 2500 HD LT3 CC/SB a couple weeks ago and after having DDM on my 06 2500, nearly the same day I ordered the same setup; Capacitor, 35W slim line and 6k bulbs. I have looked at the schematic some one did but it didn't seem to work for me. Attached is a pic of what I have for a setup. I have tried reversing the polarity on before and after the capacitor. Nothing has worked. I am sure it's user error but I could use some help. The only way I see it going together is the OEM harness to capacitor, to ballast to light. Am I missing some thing?
Thanks for the help.
