2004 Yaris 1.0 5 speed gearbox

[johnnyjm]

Having located a 2002 gearbox for it locally, there are a few differences on it, 1 being the speed sensor which on the 2002 is an electrical connector and on the 2004 gearbox that is in the car that is blanked off. Does the 2004 model read it from the hubs rather than the gearbox and if i leave it as it is and fit the 2002 boxwould it work away ok?. Hard to know with these gearboxes as to whats what.
