Can't We All Just Get Along

One of the most difficult things to figure out when modifying stock components is how to make everything old work with everything new. In order to maintain the front brake light I drilled a hole in the perch and fitted an oem brake switch inside. 

There are many obstacles any time you make a modification because so many parts are interlinked. Take for example the led turn signal indicator in the new speedo. The fact that the oem wiring is set up to reverse polarity to the indicator made the led only work for either the left or the right but not both. Since led's only work with polarity one way, extra diodes and a slight wiring change was needed to make everything work properly again.
