Went manual swap and cant get vss to read at guage or ecu

Hello im doing this for a buddy of mine .i went ahead and built him a k24all motor k24 k20 setup and had it running really good with the auto tranny streetuned using end user on the auto RAD ecu ,so fast foward a year later and we finally have it running with a manual tranny and here comes my problem
The main issue is that vtec doesnt engage anymore ever since we went manual conversion. The main reason for this I believe it becuse I have no speed sensor. So in short i believe making the speed sensor cummunicate with the ecu will fix my issue. 05 accord trans btw
I know the vss consist of a 5v wire ,a ground ,and a signal wire to the ecu.
I have the vss sensor outputting from the center wire outputting to the ecu" A 18 " pin. And with the car running i can tap into that wire on the ecu and see that it gives voltage to the ecu anywhere from .09 to 4 volts depending on speed. But the ecu still doesn't say its getting a vss reading(via scanner live data) and neither does the cluster.
Can any one shed some light here my only thought after being at this for hours is that the 05 rad ecu doesnt get "input vss" on a18. ......
