Low Voltage to the coil
IF you are running a newer 4 pin ECU, you can use a 2 pin resistor
Just trace the wiring. The wires at ONE end of the old 4 pin resistor will be jumpered together. SO that goes on one end of the new 2 pin resistor
On the other end of the resistor, (the end with the "U" shaped cutout in the ceramic) one wire feeds ONLY and DIRECTLY to one pin of the ECU. This is the un-used wire of the 4 pin ECU
If your ECU only has 4 physical pins, you are home free. IF it has 5, you'll have to use an ohmeter to see if the "5th" pin is internally hooked to anything

4 pin ECU, 2 pin resistor:
Notice the "blank" in the connector pattern of the ECU
5 pin ECU/ 4 pin resistor
In this diagram, the wire off the LOWER LEFT of the resistor is the part that is eliminated with a 4 pin ECU/ 2 pin resistor
