This one looks more like it, although again, would prefer to see a better picture

The positive keys on the outside and the dual slots in the centre certainly look correct (vs the other linked which is definitely not a match)

OK, Here are a few more shots.
The cable is short and it's hard to hold it and take pictures with my phone so let me know if there is another angle or side needed to make a match.
The last one is receiving side on the fuel pump assembly under the tank.

Thanks!

Yes, that's the one I linked
OK, thanks for the assist.
Rather than try to match the existing wires I will buy 4 color matched 20 gauge wires from them, build the connector, and splice it to the current wires.
I will also apply some liquid tape to the new connector to strengthen the wires.

Much appreciated.

I ordered several colors of wire & the connector. Parts = $6.50 Express Shipping = $9.50 so I will have time to install it before liftoff for the big trip.

OK, I received the new fuel pump connector and had a friend help me assemble the pins and new wires (using solid purple, solid grey, solid black and solid red).

I plugged it before splicing it to the harness and it fits - yeah! Correct plug and pins seem to be installed properly. Thanks @DEcosse

Unfortunately, I then sniped off the old connector and am now confused as to what pins the two black wires go to?
Does it matter? If so why are they the same color? Why two Ground wires?

I don't see any distinguishable markings on them.

The Fuel Pump is #30 in the wiring diagram.

PW = Purple & White -> Pin 1 - OK spliced in
BG = Black & Grey stripe -> Pin 4 - OK spliced in
B = Black -> Pin 2 - ? which wire
B = Black -> Pin 3 - ? which wire

Two black wires coming from main harness go into fuel pump connector.
I will splice one to the black wire and one to the red wire but don't know which goes where??

Old wire connector (white was temporary fix):

Technically the pump gets main ground and the sensor gets ECU (signal) ground - I think you'll be OK if you just guess
Thanks again.
I had a 50/50 chance of getting it right. I crimped them both in and the bike started and ran excellent for 150 miles today.
I did notice that my low fuel indicator hasn't come on. For many years, it has incorrectly come on after 50 miles of refueling so I use my trip meter.
It will be interesting to see if comes on with 50 miles remaining on the tank.
I kind of like it to stay off so I am not going to try switching the grounds around unless you see a need to.
