Just thought id put this out there for anybody having trouble with the DRL box. my auto head lights were staying on during the day when i was working on it and killing the battery. So i went and did a little research. I found that you can unplug one of the connectors and it will disable them. People on other forums said that just unplugging the "c2" connector would disable the blinkers, so i unplugged the "c1" connector and haven't had any problems. Theres a few other mods that can be done so the drl lights still work but i didn't want them. so away they went. Car works as normal and so do all the lights.

Heres the link to the forum site wher i found the info on the mod

How do I turn off automatic headlights on a 99? - LS1TECH.
(I don't take credit for making the tutorial listed above nor do i want to discredit the original poster.)

 

I don't think the e-brake warning light will work now. If you just cut all the wires at C1 except for positions D (tan/white) and E (light blue), and leave C1 plugged in, the e-brake light will still work.

 

Awesome. Thank you. that is very helpful info. lol
