Link G4+ Haltech IC7 Speed display

[Motorhead89]

Hello all, hoping someone have done this and able share some light to displaying speed on my IC7 dash in my S14 Silvia. Recently got my car tune and tuner got it to display speed with both the factory cluster and IC7 connected. Since I removed the factory cluster the speed on the IC7 no longer display speed.

From my research for the past week or so that the vehicle speed sensor (R33 rb25det big box 2 pin sensor) first goes to the factory cluster then feed into the ECU (Link G4+ plug n play) which explains why it stopped working now I disconnected the factory cluster.

The IC7 have a pre terminated pin out (Pin 33 DPI 1& Pin 30 ground output) for reluctor speed sensor, anyone had any success with connecting the VSS directly to the IC7 and calibrated it to work properly or I have to get a dakota digital speedometer converter? I know the ideal way is to send signal to ecu then through CAN to the IC7 which will be able to display gear position (once set up) also but I'm not overly fuss on that aslong as the speedo work.

Does the G4+ accept VR inputs? Someome sugguested to join pins 18 and 25 on the original cluster wiring, and ground pin 26. That will send the raw sensor signal directly to the ECU. Will have to recalibrate the sensor, as the pulses per mile(km) may be different.

Or is it possible to wire the speed sensor directly to a DI available and ground the other pin to feed signal to the ECU and calibrate it then send speed through CAN to the IC7? 

Any help will be much appreciated and thought its best to find out before spicing and wiring to the ecu/ic7, hopefully help someone else in the future.

Either connected direct to an ecu DI or the speed input on the dash should work fine.  ECU will probably be preferable so you can use speed for idle and launch lockouts etc.
