Yeah, I got nothing on a "Pink Wire" mod. The only pink wire I see, and the only one shown on the wiring diagram goes from the ECU to the injector. Green is ground in Hondaspeak, so I have no idea what TC is talking about. As posted earlier, the thread is pretty garbled. BTW, the White/Green wire shows it going into pin 28 on the 2005 service manual, not pin 27. 27 shows a Black/White wire leading to the pulser coil. It also appears that if the lights were removed at the connector, that White/Green wire would be open anyway. With the lights connected, the White/Green feeds into the ground circuit for the lights. 28 is labeled "Map SW" so a wild guess is that another milder map is activated in the ECU when the Wh/G wire has continuity. I'll have to put a meter on mine to verify, but that is how I read the schematic.
