The water-proof shroud is removed too. The plate was taken to the bench where the post was cut down using a hacksaw. The optical switch fits in the space vacated by the points with the wires passing through a grommet, shaped to fit the cutout in the distributor body. Now the chopper is placed over the distributor cam and pushed down, checking that the blades pass through the optical switch. The instructions in the kit suggest that the power module is screwed to the bulkhead but Classic are one ahead of the game here and supply a bracket to fit around the side engine frame - still no drilling.
Some tape is wrapped around the frame to protect the paint and the module screwed to the bracket.
The snap connector from the module to the optical switch in the distributor can then be pushed together. The original wire from the distributor to the coil is now redundant, replaced by that from the optical switch to the power module. A brown wire coming from the power module is connected to the negative terminal of the coil. The other wire, a red one, is connected to the positive side of the coil to join the main feed wire. Martin took the redundant wires and taped them back into the loom rather than snip them off.
