    WTB: USED SEADOO ECM/ MPEM / ECU and/or wiring harness

    Hey all... I'm looking for a reasonably priced ecu / ecm for my 04 RXP.

    From what I understand the following ecms will fit it:

    2004 RXP
    2005 Challenger
    2005 GTX 4-Tec Limited
    2005 RXP
    2005 RXT
    2005 Sportster
    2006 Challenger 4-Tec/CS/Tower
    2006 Speedster 4-Tec/SCIC/WAKE
    2006 Sportster 4-Tec

    Part number should be 420664947/420664942 Not positive though.

    I also may be interested in the wiring harness to go with the ecm. Mine were

    thanks.
