The one on the right that is theres 2 on the aux cover. Also make sure the rotor arm is pointing away from it when its ligned up as from memory if you dont slot it in right it can be facing either towards or away from the pulley!!! From memory the rotor tip is about 50/60 degrees from vertical for TDC. and dont forget to bolt the dizzy housing with the mark to where the dizzy tip is!
