Converting points to electronic ignition

I have the distributor and coil pack and want to replace my points with the elect. ign. set up but don't know where to start. Any literature out there that would walk me through it as far as inserting the distributor correctly and a diagram of where all the wires connect? It is going in a 2.0 liter Fiat 124 Spider DOHC engine.

It depends whether the replacement system is Bosch or Marelli.
There are wiring diagrams in the GC manual P 138 for both,if any kind member would care to scan and upload that would be a great help as I am a bit pushed for time today.

That would be of great help. Also, where can I purchase the GC manual for my personal use?

Is this the correct procedure when installing the new distributor for the electronic ignition?
#1 cyl @ TDC, and pointing the rotor towards #4 cap-contact

Maybe.
Essentially you should turn the engine to TDC and take the cam covers off and ascertain which cylinder (1 or 4) is on compression ie: both valves closed -the cam will be clear of the tappets (shims). That is the cylinder which is firing. You can move the HT leads around to get the firing order right. Remember to turn the crank anticlockwise (viewed from front pulley end) 10 crank degrees to set the timing because 10 deg is needed as static advance. If it fires at tdc the ignition is 'retarded'. As the engine speed picks up (about 1200 rpm and over) the springs and weights in the distributor bring in additional advance. If the distr is block mounted the direction of rotation of the rotor arm is clockwise.
You will need a strobe light to set the timing accurately, don't drive before doing that check.
