First of all I'm leaving a review because it was hard to find one to help me decide on my purchase. I bought this gear indicator for my Yamaha R1 04 Track bike. Instructions are ok. I looked online , checked with a local Yamaha dealer and they pointed out the K-line wire as the speed sensor wire (if you cut the wire the speedometer will stop working, therefore you assume the dealer and the drawing were correct). Ended up that the data sent at the cluster by this k-line is in a different format. So avoid my mistake and connect right at the connection of the speed wire sensor (white and yellow IN MY CASE). The rpm, ground and positive get them at the cluster, so you only have to extend one wire (the green one). when connecting the wires correctly it worked perfect the first time setting it up. A piece of advice solder all the wires except the positive, so if you need to re set the unit you won't have to turn off and back on your bike, after you are all set, solder away. I set it up with mi bike on a stand. Pegasus was great about taking back the item (I was going to return it, but I didn't). Neil Armstrong (UK technical service) was AMAZING walking me through every step and helped me to figure out the color of the wire. Very happy with His help and professionalism. There are cheaper units out there, but none as solid as this one and I really like the increasing LED as the rpm goes up. I hope this helps someone. Now go ride that thing!!
