Experts, I'm installing an aftermarket speedo that needs to tap into a wire from the CDI for the RPMs. Looking at the drawings it appears to me that the Black/White wire is the one to use, but just need confirmation before making cuts. Thanks.
Here is a pic of where I spliced a white wire into the blue wire for RPM connection in the cheapo speedo. When I started it on the weekend, there was no RPM reading. Before I start trouble shooting in the wrong direction, have I missed something obvious or spliced into the wrong wire?
