After you have completed the Duraspark distributor conversion by following this thread. CLICK For Non-Fuel Injection Now how about something easy for the ignition. Here is the DS distributor running a GM 4 wire ignition module. Now you get modern electronics (same as the $$$ HEI Distr has) that are available in every parts store. As a preview, Here is a little teaser video showing my conversion avail direct, using the optional round HEI coil. Duraspark conversion video I also recommend the voltage to the coil be directly from a power relay so it receives full battery voltage and just use the original key switch wire to energize the relay. Ignition Module PN- EL102 NOTE: ignition module MUST be mounted on a heat sink like 1/8" alum, and it MUST be mounted with thermal conductive paste(CPU mounting paste). Do not use the parts store dielectric grease. The heat sink should also be bolted directly to the engine to provide a good ground for the module. The module grounds through the mounting screws so both must be installed. Here it is installed by John H. Ford Duraspark Ignition Plug the Ford Duraspark ignition module into the distr harness and wire in the 12V. This was my first major change to my scout when the GB died. Part Number: EL107 Vehicle: 1979 FORD F-150 PICKUP Engine: V8 5.8 Liter 2BBL Module; OE Style; 351M Engine; 351W Engine; Except High Altitude Distributor # D6AE-12A199-A1A/A1C/A2A/A2B/A2C; D8VE-12A199-A1B/A1C/A1L/A2B/A2C; E8PF-12A199-AA/AB Our Price: $19.48 You can grab the wires and the ignition box from the junk yard when you get the base plate. I normally pay $10-$15 for everything. If you look around, sometimes you find some near new replacements parts hiding in there! The later TFI coil is another option while you are grabbing parts. It's an epoxy core coil so there is no oil. Like the GM coil. Used by Jeep guys with DS. Part Number: FF179 Vehicle: 1988 FORD BRONCO Engine: V8 5.8 Liter FI Ignition Coil: Windsor Our Price: $21.99 Here is the wiring. (view in normal mode not dark) EDIT: white wire should go to S terminal vice I terminal. Duraspark troubleshooting guide If you want MSD with the DS pick up!!! HEI trouble shooting Distr pick up coil Ignition coil ----------------------------------------------------------------------------------------------- For Fuel Injection here is the wiring diagram to connect your DS conversion to the 8 pin EST. Thanks to Brendan for the diagram. HEI trouble shooting Note: When setting the timing for the first time you must ensure the wiring is correct on the ignition module. The 2 wires from the pickup in the distr must be connected to the proper terminal, P and N on the module. To verify they are correct: A. Set engine to TDC compression stroke. For IH use #8 for V8s and #1 for 4 cyls. For all other makes use the correct plug. B. Remove the cap and verify the rotor phasing is correct IAW the distr conversion thread. Rotor should be just past center of the cap terminal in the direction of rotation(clockwise for IH) and the reluctor should be lined up. C. Connect timing light and disconnect the timing bypass connector if EFI. D. Crank engine to check timing. If the wires are connected properly then the timing will be within 5* of 0*. Just set timing to 0 and your good. If the timing is 20-30* away then swap the P and N wires and check again.
