Low Voltage to the coil

I thought I did. Look at the above two diagrams.

Notice that on the bottom diagram THE TOP END of the resistor is jumpered across. One of these connectors will hook to the new 2 prong connector. So if there's a dual connector there, you can either leave it, or cut right at the connector and replace the one end as necessary

The only other thing you do (for appearance) is remove the ONE wire shown in the bottom diagram, that goes from the BOTTOM LEFT of the resistor, down to the ECU connector.

You don't HAVE to do this---it's only for appearance. You can actually just hook the new 2 pin ballast as indicated to the "right side" of the ballast in the bottom diagram. The one wire going to the "5th" ECU pin will simply not connect to anything.
