My truck doesn't have automatic headlights. I actually want them to come on anytime I'm driving. Can I simply use a switched hot to operate a relay to interrupt the signal from the switch to the control module? It seems simple enough but I'm not sure how all of that works with the module. If so, which wire would I need to interrupt off of the switch? Thanks in advance.

 

Why not go to dealer and ask them to turn on the Daytime Running Lights (DRL)? Tell them you feel it is a safety factor for you and maybe they will do it for free. It is a programmable parameter in the BCM.

It's even easier than that. Simply go to the dealer, and request to have your DRL lights enabled with IDS through the programmable parameters function.

 

Well by golly, that sounds pretty easy! Thanks.
