Firstly the dizzy rotates clockwise viewed from above.
The firing order is 1/4/2/5/3/6, the cylinders are numbered on the OFFSIDE front to rear 1/2/3, and on the NEARSIDE front to rear 4/5/6.
Now looking at the dizzy at the rear of the engine the vacuum capsule should be pointing straight at the offside wing, and no 1 cylinder lead would be nearest the bulkhead, the last cylinder no 6 is the one nearest to the vacuum capsule body.
Hope this helps.
