Bypassing ballast resistor
Top / bottom doesn't mean much because I don't know how the thing is mounted.
Basically you have two resistors in one box. "The end with the loop" is the ignition feed and feeds power to both resistors. One goes to the coil, the other goes to the ECU. Use your ohmeter or follow the wire from ECU back to the resistor, and you can just eliminate "that side"
In the drawing below, what you can eliminate is on the left side. The "remaining wires" all get spliced together. What is NOT shown here is the coil bypass wire which goes from the bulkhead to the coil+ side of the resistor. "Colors vary" over the years, traditionally brown
