I am pretty mechanical and electrically savvy. I also understand the instructions that came with the modulator. I am all set to spend hours, if neccessary, to track wires with a multimeter. I do not have a service manual. My problem is... I removed all the faring plastic, yea, all of it windshield, mirrors, dash, speakers, etc. I had yellow plastic scattered all over my garage. This is crazy! I can't find access to the headlight wiring to save my life. The best I can do is reach down next to the risers and pull the plug at the headlight and make the most fundamental connections which won't allow some of the cool functions of this modulator, like the light sensor, etc. Does anyone have this T-shirt yet?, (wiring diagram/schematic) or the majic hole that opens up to the wiring for the lights. Thanks for any help!
