Does anyone know what the wiring diagram would be to wire the shift sensor to the brake sensor and do they use the same type signal source?
I have a Shimano 11 speed IGH and find that I need to stop pedalling for a second or so to allow the hub to change gears. This can cause a loss of momentum and riding rhythm. This is partially due to the TSDz2 continuing to power the drive even though I am only applying a little pressure on the pedals. Unlike a Rohloff, the Shimano IGH does require the force on the IGH to be significantly reduced to allow shifting without mashing the gears.
If the 3 wire gear sensor can be used with the 2 wire Tsdz2 brake sensor sockets on rear of the VLCD5 screen, this might allow enough period of loss of engine force to allow the IGH to change gears. Of course the rider will also need to reduce the force on the pedals, but hopefully not need to stop pedalling completely as is currently the case.
(I do not want to use the 'Speed sensor' option as is used by revher, as my bike doesn't use the 25km limitation)
So my question is the same as 'jeff.page.rides', any suggestion as to to what the wiring connections would be to connect the 3 wire gear sensor to the 2 wire brake sensor on the VLCD5 display.
My testing indicates the brake switch is 'open' circuit when the brake is not applied and goes 'closed' when brake applied. There does not appear to be 5v at either of the brake sensor pins on the VLCD5 display. So maybe the two pins on the VLCD5 brake sensor can be connected to the gear sensor ground and signal wires, and I need to find a 5v source for the remaining wire on the gear sensor.
If I can obtain the wiring details, I will fit the gear sensor to the gear cable where it exits the gear changer mechanism on the handlebar, as it is only a short distance to the VLCD5 display.
Cheers Emma
I found this item, which appears to be what we need for the Gear shift sensing as it connects to the existing VLCD5 brake sensor sockets, but it doesn't appear to use 5v source. Unsure how it can work without the 5v. It also has brake sensors suitable for hydraulic brakes...

Hi Emr
Did you end up using this gear sensor? I am also looking at getting this for my wife bike. She has a Nexus 7 and due to the motor continuing after she stops pedalling she is grinding the gears. I'm keen to know how this works before ordering it.
Thanks
