The idea is to run a wire from the test point GND to the left pad of jumper J1. Then cut the trace between the J1 left pad and the R46 right pad. Then get 5V from the right pad of R46.
It sounds messy but would allow me to put a 3 pin connector on the board for connecting to the hall effect throttle.
Hope this is right because I already made the changes! Here are some pictures to help clarify.
Before powering on the board I wanted to double check that the J1 left pad is not connected to anything once the trace is cut.
Here is the ground wire:
And the 5V wire (The bottom of the left most pin on the 3 pin connector is bent and soldered to the red wire):
