Fuel Pump/Sender Connector

[PleiadsMan]

Hey everyone, I'm almost finished with the harness other than the lights and some minor things. I'm at the rear harness and need to wire up the pump and sending units using FFRs supplied connectors to the cars harness. I'm stumped with the sending unit, I know the fuel pump Power is black and yellow and the ground is black on the fuel pump unit connector, but what would the sending units power and ground be on this connector?

I have a 2006 WRX donor.

The sending unit is just a resistor, there's no power. The sender should read 1-5 ohms at a full tank and 92-96 ohms at empty.

Gotcha so no power, but where would it be wired to to read the resistance. I basically have the green wire and have no idea what wire it needs to be connected to.

There are 4 more wires 2 blue red and a brown. One of them is a ground and one is signal, anyone have a stock sending unit where they can trace the wires to the pins to the harness?

Sorry, I don't have the wiring diagram for an 06, I only have the 02 and 04 diagrams. The answer should be on the "fuel gauge system" page. On both of the diagrams I have, the sender is grounded on one end and the other goes to the gauge cluster and splits off to the ECU. If I had the 06 manual, I could tell you which wire colors go where. Here's an example of the 04:

For the Fuel Gauge System:
use only the #2 pin, BW on the plug you show, and use #1 pin BrW on plug R59. I went back all the way to B99 to grab my wires (Pin 3 and 11)

Thanks! I want to elements as many plugs as possible, so I'll try and trace all the wires for power ground and signal and try to dig into the main bulk of wires.

Thanks again Slava and matteo92065

Boy, we don't think alike.
I add plugs to make things easy to take apart.
For instance, I add one 12 pin Deutsch connector for my whole rear bumper.
All the little double arrows in my lighting schematic are connector pins.
Everything in red is on my rear bumper. Green is left front and blue is right front.
Black in in the dash.

I ment to say eliminate as many non necessary plugs as possible. Hoping tht the fuel level sender wires are the only wires I need in that whole harness, I would much rather just take them from an earlier plug and eliminate the other harness altogether! :) weight savings!
