All the 'Hall effect'electronic ignition modules are very easy to fit. As it is easier to fit with the distributor off the engine, turn the engine so that the rotor-arm is pointing in a rememberable position (I normally have it pointing UP). Remove the distributor, remove all the gubbins inside the distributor and fit the ignition module as described in the fitting instructions. Personally, I always obtain a new square 'exit' rubber for the wiring (out of the distributor---they are supplied with round 'exit' rubbers) and secure the wires with a very small cable tie just inside and outside the distributor. The red wire goes to the +VE (15) terminal on the coil, and the black wire to the -VE (or 1) terminal. Just to stop them flopping around, I normally put both of the wires, and the oil-pressure warning light wire into a 'split' sheath.
By refitting the distributor with the rotor-arm in the same position, the engine should start and run pretty well, but to check the timing with the electronic module you MUST use a timing light. Hope this clears up your concerns.
