Toyota 86 GTS Headlights Pinout Diagram

Recommended Posts

Hi guys, I've been playing around with my Toyota 86 GTS headlights, figuring out how the DRLs dim.

It seems that there's a 14V trigger wire that causes the DRLs to dim.


However the regular 14V maximum brightness DRL wire starts doing a supposed square wave 5V RMS when the "dim DRL" wire has a 14V through it.

Please find attached the diagram (PDF and PNG format) I have drawn up. I was hoping to get some more opinions on this.


I'm figuring out how to dim my switchback DRLs :P
