Old thread, but still hot...
I bought an EXC tripmaster switch because I found the plug among all wires behind the headlight. I have an '07 SE, and it plugs straight in. I was excited to see if I also had the pin #14 problem, but not so. All three buttons are working.
But I should have read this thread better, because I'm a little dissapointed. Sure its a must to increase or decrease the total in trip 2 when doing roadbooks. But what about trip 1. I use trip 1 between the different checkpoints and need to reset it to 0 every time. So the tripmaster switch only is good in trip 2 mode? I still have to reach down on the tripmaster panel and press reset?
