Question about electronic part of the VSS on a '94 B-Series

[Guanfy]

My question is that do you actually need the electronic part if you have a manual transmission? The speedometer is cable driven so are there any instruments that require the connector there in the tailshaft of the transmission?

There are feed forward protocols in certain engine calibrations that can cause driveability issues...erratic idle, stalling ect....but generally after awhile the engine adapts...
