I'm looking for them too cause mine's not adding fuel in the midrange.
I'm thinking I have a bad wire some where on my stock harness, just haven't found it yet. I'd like to see the instructions though just to make sure everything's right.
Here's where mine go. Silber installed the kit himself.
Unplug the ECU plug closest to the motor and cut the yellow, green/white, green, and yellow/white wires. Leave enough on each end to splice into.
Controller wires...................ECU Plug
Yellow........................................Yellow
Green.........................................Green/white
Gray...........................................Green
Blue............................................Yellow/white
Controller wires..................... Harness
White/yellow..................................yellow
White/green..................................Green/white
Green/gray...................................Green
Red/blue......................................Yellow/white
Red (power) wire to the thicker red wire on the white plug further towards the front end of the clutch gaurd
