I accidentally starting messing with these wireds to see if any were for the headlights (i was trying to install interior led lights) and all of my dashboard lights are now going off like crazy (airbag, check engine, battery, sliding, etc), the a/c and heater doesn't work, the turns signals don't work if i step on the brake, and it no longer indicates what gear i'm in. I really messed up, but I would like to know if anyone has had this issue or knows a solution or what's going on.

YIKES!!!!

Check the Dome and ETCS fuses in the under hood fuse panel. Hopefully you popped one of those and didn't cook the ECM. The DLC3 connector is purely for diagnostics. There is a constant power wire on the connector for powering a diagnostic tool, but other than that no pin on that connector should ever be connected to a load.

Hi,

I recently purchased the Vitz 2007 model. It has DVD and CD Player which works great. The problem is that this device panel lights don't glow even when I turn the parking lights on. Here is how my car DVD panel looks like:

I had the car checked by local Car Audio Workshop and they technician guy looked at the wiring and said that these are okay. What else could be the problem?
