Attention: TDR Forum Junkies 
I'm trying to wire in a marker light interrupt so I can flash my marker lights only.
I've been looking all over the service manual and apparently, the headlight switch sends a signal to the Front Control Module which provides a signal to the Lamp control relay which switches the lights on and off. I can't get to the supply power to the relay as it is part of the fuse box. My question is: Is there a way to determine which wire out of the headlight switch to tap into to interrupt the marker lights? Has anyone done this mod? I just need to know which wire sends the signal and hopefully, I can just put my switch (relay actually) inline without messing up the front control module.
