    Polaris ignition update

    Im installing the update kit in to my 99 sltx 1050 and theres two wires left that dont match the grey wire with a female spade end coming from the CDI and the big brown wire coming from the bike with a male end they will plug to each other but they r different colors and they are the only ones left..??
    and what ground do i get rid of, im assuming the one in the front box where the electronic board is?? i dont see why
    thanks,

    Tan = RPM limiter signal = Gray wire.

    Connect Tan to Gray, should work correctly like that.

    When installing the Polaris Ignition System Upgrade Kit for domestic engines, the ground wire to remove is the thin Black wire between the battery negative post and the electrical box.

    All Black ground wires within the electrical box are to remain connected.

    so the main one that goes to the board correct? im guessing the new CDI has a different color wire then the old one?

    Not sure which wire you are referring to here

    Polaris used both Tan and Gray wires for RPM limiter function. The newer domestic CDI have gray wires for RPM limiter signal.

    The thin Black ground wire that gets deleted is the one with the ring end for the battery terminal bolt.

    Coil that black wire up and tape it aside, or better yet, cut it off at or near where it enters the electrical box.

    Exactly.

    Removing the direct link (thin Black wire) between electrical box and battery negative forces all grounding of electrical box equipment to ground through the Black stator wire, which grounds to the engine block through the stator mounting bolt(s).

    The primary upside to this change is that if the main ground connection of the heavy black battery cable goes bad (which can happen), the thin Black wire (that has now been disconnected) will not become a fire hazard. The original Black wiring arrangement carried the risk of electrical overload for the small wire if the main Black battery cable went bad.
