I've spent hours searching forums, trying to figure out how my DRLs were wired, but I just can't seem to find the answer. Here’s what I know so far:

Vehicle Details:

• 2005 Acura NSX (originally a U.S.-spec car)
• Imported to Canada, where a previous owner had DRLs installed to meet legal requirements
• Modification was done by a shop, and it was reportedly a quick process

Current Behavior:

• No Key: All lighting functions operate normally—I have full control over low beams, high beams, and running lights.  When I turn on the high beams BOTH the low and the high beams are on
• Key to On: The running lights and low beams turn on automatically. I can toggle the high beams on and off, but I have no control over the low beams.  This information was wrong....it is JUST the low beams that come on...nothing else.  But when I turn on the high beams BOTH the low beams and the high beams are on.

Troubleshooting So Far:

• Fuse Position 3 (Cabin Fuse Box): Empty
• Interior Disassembled: I currently have most of the interior out for a stereo upgrade and sound deadening, but I haven't been able to locate where they tapped into the system.
• Fuse Boxes & Wiring: No visible modifications under the dash or in any fuse boxes.

I’d appreciate any help in tracking down where this mod was installed!
