ROTOR PHASING
22. Rotate the engine backward to 22-25 degrees BTDC. Make a small mark on the outside of the distributor housing where
the rotor tip is pointing.
23. Install the distributor cap, and locate the spark plug terminal that is closest to the mark on the outside of the distributor
housing made in step 23. This is the terminal for cylinder #1. Mark the distributor cap to indicate the location of the #1
spark plug wire.
24. Remove the distributor cap, loosen the two 5/64” Allen-head screws slightly and adjust the rotor so it is pointed at the
center of the terminal for cylinder #1. Tighten the two Allen-head screws to re-secure the rotor.
25. Install the distributor cap and spark plug wires. Double check that the spark plug wires match the firing order previously
set in the ECM.
26. Reconnect the injector harness.
27. Connect the Dark Blue wire from Pin “H” of the 77101 harness to the points/trigger lead of the ignition enhancer module
(Example: DFI 6A DK Blue – ACCEL 300+ White Wire – Mallory 6852M White Wire – MSD 6A White Wire)
DO NOT ATTACH THE DK BLUE WIRE MARKED EST TO THE COIL!!!!!!
IF YOU ATTEMPT TO DO THAT, YOU WILL CAUSE DAMAGE TO THE ECU.
Next, connect the pink wire from Pin “A” of the 77101 harness to the switched 12 volt input lead of the ignition enhancer
module (Example: DFI 6A Red/White Wire – ACCEL 300 + Small Red Wire – Mallory 6852M Small Red Wire – MSD 6A Small
Red Wire).
DO NOT ATTACH ANOTHER SWITCHED 12 VOLT SUPPLY TO THE BOX
28. Start the engine. Using a timing light, verify that the timing reading on the harmonic balancer is the same as the timing
reading in CalMap. We recommend forcing the timing in CalMap to 10-20 degrees while verifying readings. If the readings
are different, loosen the distributor and rotate the distributor housing until the timing readings on the harmonic balancer
are the same as the timing reading in CalMap. Tighten the distributor.
Your Dual Sync Distributor is now correctly mounted, phased and ready to run Sequential Fuel Injection.
