Once you have bolted the unit in place, you need to run the wires out of the crankcase in the same place that the stock wiring comes out. This will allow you to put the crankcase cover back in place when you are done.
The Dyna S uses three wires. The red one goes to an ignition switched hot wire. The black and white ones go to the coils.
As you look at the unit when it's bolted in place, the trigger (rectangular black plastic box) on the left is for the Cyl 1 and 4 coil. The right hand trigger is for Cyl 2 and 3 coil. Look at your spark plug wires and figure out which coil goes to the No. 1 and 4 spark plugs. This is the Cyl 1-4 coil. See if it has the yellow wire or the blue one. Can't remember myself. Then look at the wire coming off the Cyl 1-4 trigger. It'll be white or black. that needs to hook to the yellow or blue wire to match things up. The remaining wire obviously goes to the other coil.
There are three screws that hold the unit in place on the end of the crank. Loosen these up slightly to allow the plate to rotate. take the no. 4 spark plug wire off the plug and put another spark plug into the end of the wire. Rest the plug against the block to ground it out. Turn on the key and SLOWLY turn the large nut on the end of the crank in a clockwise direction. You will be able to hear the spark plug actually spark. Check thru the sight hole on the Dyna backing plate and see if the 1-4 F mark is in line with the index mark. If not, then you need to rotate the plate slightly clockwise or counter clockwise and check spark again. Eventually you will get it to the point where it fires the plug on exactly the 1-4 F mark. Tighten up the three plate screws. Then pull the wire off the no. 3 plug and repeat the above procedure. However, instead of rotating the whole plate, take the little tiny allen wrench that comes with the Dyna S and loosen the screws that hold the 2-3 ignition trigger to the plate. This will allow the timing for the 2-3 coil to be set seperately from that of the 1-4 coil.
That'll get your timing spot on. You can check it with a timing light when the engine is running to make sure that the advancer unit is working.
