    Tach wire has to go to the tach output of the Sniper, not to the CD box. It says so somewhere hidden-ish in the documents.

    Yes, the dark brown wire is the Tach Output: http://documents.holley.com/199r11031r.pdf (Holley Sniper EFI Instruction Manual - "ECU Wiring Overview", Page 17 & "10 Pin Connector", Page 18)

    It's a shame they didn't add the brown wire to the main 7-pin harness, now I have to connect the 10-pin just for one wire.

    Well, it's not used in ECU controlled timing with CDI box applications.
    May God's grace bless you in the Lord Jesus Christ.

    Unless you're going to make use of any of the functions necessitating the use of the 10-pin harness, you don't need it at all. Just splice into the Tach Output wire from your CDI box, and run one wire to the Tach and the other to the Ignition Adapter. The brown wire on the 10-Pin Harness is merely a pass through to facilitate the use of the 10-Pin Harness for those ancillary functions. I have mine wired in this manner and it performs flawlessly. You've managed to make this simple installation very complicated, and Danny has displayed the patience of a saint answering your questions. Hats off to him!
