IS it possible to split the feed from one speed sensor to supply the both Gear Indicator and SpeedoHealer?

Yes, thats how it's usually done. Never heard of it done any other way.

Speedo healer is in series between the sensor and speedo and the gear indicator is on a spur either before or after the healer (pretty sure it doesn't matter which).

I would split it after the speedo healer, because that should be a much better defined signal

Great thanks.

Yes i was planning on splitting after the SpeedoHealer.

So its actually the speed sensor that came with the GiPro that i will be using.

Trust this will work for the speedo side of things? As i don't have the speed sensor on this old Blade engine.

So im going -

Speed sensor --> Speedo Healer --> Gi Pro (With signal split off to speedo)
Green black wire from Gi Pro --> Tacho Ylw/Grn or Pulse Ylw wire
Red and Black from GI Pro --> Live and earth


Someone correct me if thats wrong..
