Gear indicator install help?
I'm buying a Healtech gear indicator for my track bike, because it has the HRC ECU i can't buy the std version that simply plugs into the diagnostic port, bit of a bummer but not the end of the world.
The universal loom they offer is 4 wires, pretty basic stuff, i have to find Pos (9V min), Grd, Tach signal and Speed signal.
Seems straight forward, and the first three i can easily find in the instrument cluster loom, the speed sensor wiring i'm having trouble with, i haven't touched the bike yet as i don't have the part in hand, nor do i want to disassemble until i'm ready to install it but i'm looking for clues on whether or not anyone knows if/what the speed sensor wire is in the back of the gauge plug?
I know the Gauge displays speed when ridden so it has to be getting there somehow but the wiring diagram i have is a scanned copy and i can't find anything that says speed sensor on the schematic.... the wiring from the sensor doesn't follow to the gauge cluster directly and i can't see anything that clearly shows it running via the ECU either.
If no one knows i'll just bell it out with my meter from the speed sensor to the gauge plug but if anyone has done this already some guidance would be appreciated.
The last thing i want is extra wires running any further than they have to, i like the idea of a short run from the display (with the gear indicator on the side) to the front harness, nice and clean and tidy...
This is the wiring for the std cluster, the HRC loom which i can't attach doesn't have hi-beam, HESD-IND, SP and SP_Vcc shown in the schematic
