Is there an easy way to disable the DRL but all the functions of the light in park and headlights still function ?

 

not that i'm aware of ...i'm pretty sure it's controlled by the BCM

 

dito.... if anything ya might have to rewire the headlights completly.. wire up 2 relays off the battery and use the stock switch to control the relay and run the power output wire from the relay to the headlights.... low beams and highbeams. use the one as low beams and one for the highbeams...
or ya might only need to do one high or low... not sure how the DRL lights operate off of... i think only one but not sure if it runs off high or low beams... test light is your best tool.......

 

been searching and reading
seems like fuse #37 if removed from fuse box will disable DRL

 

On the 06 and 07 this is correct. It's a 7.5 amp.
