I dont think you can use the 4 pin module to control timing.
I did mine by taking out the 4 pin,weights and springs, and tack welding the plates together. The two sensor wires I ran outside the dist, and hooked it to an 8 pin module from a 90's GM. Mounted it outside the dist. Will work on its own just like the 4 pin, but has a tach out to go to the ECU, and another wire that you can hook up to tell the module via the ECU to command the timing values.
I pretty much did this, just started with a Pontiac dist.
