When you mount the Opti with the guide pin you just arrange it the way it looked like when you took it off or?

 

Yup, just look at the mating portions and it's pretty obvious...be sure it slides on easily. It may engage firmly, but does not require excessive force. If it doesn't sit flush, pull it off and try again, DON'T use the bolts to pull it on. Double and triple check your connections to it afterward, it's a common mistake to have some plug wires swapped.

 

The opti should look like a clover.............on one of the "leafs" it looks diferent, it has a square off the top of the leaf.........that is where the cam dowel needs to lineup.
