I did the F/T DRL's mod today. It took me all of about 5 minutes.
I did a search and found the thread.
Thanks for the info.

 

AWESOME!!!

Yeah, very easy but COOL mod!! Congrats!!

 

i believe that was bob with the detailed description on how to... I also used that thread along time ago. works good

 

what is this mod you speak of? I only know LS1,2,& 6 mods. Thanks

 

this mod will turn on the DRLs when the parking lights come on. you put a diode between the drl and park light relay so that when the park lights come on your drls stay on. there's a good write up on here somewhere that shows the 2 relays and exact pins to connect the diode to. as long as your parking lights are on, the drls will stay on, so that means they're on when the headlights are on too.
