the zetec sensor is a short stuby little thing and a frst/efi cvh uses a long sensor
zetec one wont register as its too far away from flywheel
cvh one you need the bracket that goes on the block for the cps to go too
if you dont use the bracket the cps is to long then and the flywheel will chew it up
i also think that the 2.0 dohc injection from sierras sues teh same cps as a cvh
well all mine dohc has used long sensors
