If anyone has an 00-05 MonteCarlo/Impala, and you are looking for a way to disable your Daytime Running Lights (GM does not provide a way to disable them like most cars/trucks), a friend of mine has devised a solution.

He has built a circuit that will take care of this issue, so if you are looking to have this option to disable/enable your DRL/ALC system at will, please follow this link to the NAIOA forums and contact him.
