I just installed mine last week and LOVE IT. I got the Blue LEDs. Works great!! Follow there instructions as given in a link above. The yellow wire with blue stripe is tach wire coming out of the back of gauge cluster. There is a set of wires on the right side by the right air intake with a connector on the end of it unused. It is switched and that is what I used. I know one was brown w/ white stripe and the other was black w/ white stripe
Again the instructions above in that link are thorough. Any help just write
