IF you don't have a tach, four leds is all you need. This install is universal for all Contours/Mystiques w/o tachs.
Yep, cheap ebay idiglos but they look real nice. The install is pretty easy and there are plenty of topics on it around the forums if you need help. I installed mine within an hour w/o instructions.
