yeah, denso diagrahm offers 2 connection types for honda, however, the connector type that i have uses blue to white and white to green. i don't know how its wired up internally.. maybe it don't make a difference if you swap the 2 with one another.. but i'll go with what DeDonDeRosa says and diagrahm. thanks all for helping
