Hello � I�m trying to troubleshoot an EFI engine light on a Yamaha GTS 1000 (1993).
Can anyone tell me where to purchase an �EFI test coupler� Yamaha part number: YM-3149 or 90890-03149 The part number came out of the GTS service manual, but the local dealer here in Denver cannot find a listing for the part Thanks, R Huggins
