Fuel Pump Electrical Adapter
93' Bronco XLT
5.8l
What I need help with:
Fuel pump replacement comes with new connector which requires soldering new adapter to vehicle wiring.
Instructions that came with adapter refer to wire colors that my vehicle does not have.
Have measured voltage on all 4 wires. 2 are ground, 2 are power.
1 power for sending unit, and 1 power for fuel pump itself. Both are continuously energized.
1 power reads 7.5v and the other 6.7v.
Anyway of determining which power goes to sender unit?
