Has anyone bought one and installed it? I just recently got one and having trouble wiring it up.
Thanks for the help!Well, it sounds like you have it wired up correctly, if you're getting any response from it at all.
For the fuel gauge, the fuel level sensor wire is the white one.
For the tach, the black wire is the signal wire and is shorted to ground every time one (can't remember if it's the front or the rear) coil fires.
I'm just spitballing, and maybe someone else has a better idea, that maybe the IC box that controls the spark timing doesn't provide a clean square wave signal on the black wire, which may be causing problems for the digital tachometer? You might be able to find some sort of filter that would clean up the signal a bit before it hits the tach. Maybe just cleaning up the connectors at the IC box and ground would give you a more decisive path to ground more stable signal.
Those brown wires are the +12v lines when the ignition switch is "on". You said you were already pulling power from the ignition switch to the new module, so those leads are just extraneous now. Cap 'em.
Thanks guys. A lot of great help. Hopefully I can figure out the issue this weekend because it’ll be nice to ride here in the SF Bay AreaOnly caveot to lack of power wires is if you're on an underpowered line. You may not be on a line supplying proper amperage or voltage into the cluster. Check and verify voltage with everything on and running. If you have a voltage drop at the unit with it on, but proper voltage coming in with it off, your supply in line isn't keeping up with demand. A weak ground can simulate this effect.
