yea arumndark understood me because when i release my handbrake drls turn on and override my park lights. i dono maybe i wil disable my drl's
disabling the DRL is just one simple snip of the wire - though make sure you cut the wire and can still reconnect the two pieces.
the only way to have full control over the headlights is to disable the DRL. (fog lights are a different subject)
what year celica do you have? for the 2000-2002 celicas, the wiring should be the same as the one in the guideline (for both the gt and gts) (it worked for me)
