Okay, i'm immensely interested in this because I have some halo projectors on the way and want to be able to idle or show off the halo LEDs in my headlights at night.
So i've seen the thread already that says how to disable them. And i'm not interested in making a switch to disable/enable them. I can remember on my own to turn on my own headlamps at night ^_^.
The issue i'm running into are conflicting details on how to properly do it.
Doing a bit of googling reveals a few things. Obviously the wire box under the steering column above the brake pedal controls these features, the DRL and automatic night time headlights.
What isn't so clear is what a proper procedure and what the proper wires to cut are for disabling both is. I have read that if you cut the 12 pin red wire it disable DRLs and possibly automatic headlights. But i'm not sure. Others suggest cutting a yellow wire to disable both, but I am not sure which wire that is. It might be the yellow wire in the included picture but I can't be sure.
Lets get some discussion going and find out WHAT NEEDS TO BE CUT SPECIFICALLY to disable certain features.
To disable DRL, cut: "i believe that cutting and grounding the yellow wire was for DRL disable for 03-04 corollas" -TrdSpeed140
To disable BOTH, cut: "I cut the red wire on my 06 to disable DRLs and auto on..haven't had any issues" -constricted
It is supposed that disabling DRLs eliminates automatic night headlight functionality.
Lastly, will editing any of these features screw up dash lights such as gauges and the climate/radio controls?
