Showing the distributor as it would be mounted on the engine, but now the contact breaker plate is reversed so points are at the top making adjustment and timing much easier. ( If oil seal fails on distributor shaft the points do not get covered in oil ). The distributor cap has a drain hole at bottom. Full written and pictorial  instructions are supplied with the kit.

Reversing the points plate is simply a matter of removing the two slotted head screws and rotating the plate 180 degrees.

The white wire is shown connected directly to the points underneath the plastic 'tophat'. The wire and support loop are supplied as part of the kit.
