Trigger Wheel angle missing tooth

The trigger wheel & sensors miss the chassis. Quite tight though.

EDIS4:
Is A or B right before I get tack welding done?
I can't get my head around it.

B should correct since you want the sensor to be 90 degrees (9 teeth) behind the missing tooth. Hopefully someone with a little more experience can chime in, but that is how I remember it.

Can someone confirm to help me please. Is the aim to tell the megajolt that missing tooth is 90 degrees about to hit the top spot.

The easy way, set the engine to 90* BTDC on the #1 cylinder compression stroke and then align the sensor to the missing tooth.

Both diagram A and B are 90 degrees after TDC, the VR sensor needs rotating 180 degrees.

The VR sensor is firmly mounted in that position.

I just need to mount the trigger wheel correct onto the pulley.

Need to make sure which one is right.

Going through the installation guide it should be option B:

1.Mount the sensor in any convenient way that simplifies bracket design and accommodates mounting points on the engine block.
2.Turn the crankshaft to precise Top Dead Center (TDC) for cylinder #1.
3.Position the timing wheel onto the crank pulley with the missing tooth aligned to the sensor.
4.Now offset the the timing wheel position:
If your engine turns clockwise when facing the crank pulley, rotate the timing wheel clockwise "N" Teeth.
If your engine turns counter-clockwise when facing the crank pulley, rotate the timing wheel counter-clockwise "N" Teeth.
5.mark this final location of the sensor wheel onto the crank pulley- then weld or bolt timing wheel into place as appropriate.

And so thinks me
