Wiring Connection for fuel pump problem

Was out on my 2005 Maristar 210 on Saturday when the boat died under power. After doing some thinking it had power but wouldn't turn over - or would and sputter. Eventually traced the issue to the fuel pump. The pump itself is fine however a wire from the boat side going into the plastic connector to the pump was coming loose. We held it together and got back to the dock. In the mean time it got hot from poor connection and seems to have damaged the plug. Does anyone have a part number for this? Only had the boat 2 months so I'm not sure if this is factory or not. Any help would be appreciated - My first thought was to just reset the wire into the plastic connector but with it discolored I'm not sure about that. The yellow is fixed to the fuel pump while the black I'm holding is movable and the side where the wire is loose. Thanks for any help

The metal inside seems to be discolored and looks like it's melted a bit of the plastic. Will try another picture. I would think I can reset the wire but I'm going out of town and figured that if the part was damaged I could order a new one and have it when I return. Electrical parts and possible damage tend to worry me

I had the same thing happen to my 01 Maristar with the 330 HP LTR engine. I had to replace the fuel pump to fix the yellow connector side. The connector on the harness side is an easy fix. The connector matches a GM IAC motor. I ordered the connector online from Autozone, it comes with wire pigtails already installed in the new connector. I cut the old connector off and soldered the new pigtails to the wires. I think I looked up the IAC connector for a 98 Chevy 1500 C/K truck with a 5.7 engine. Worked great, no problems since.

Had the same problem on my 205 with the LTR. I know the previous owner of my boat chased that problem for a while and threw a pile of parts at it but never replaced the last 6 inches of wiring and the connector that were the problem. You might be able to use a small pick or screwdriver and a pliers to adjust the metal parts that actually make contact with the pins in the yellow end. I did that and it worked till i got the new part.

Same problem here '99 210 VRS. Used my daughters hair tie for a year to keep the connection together. Finally bought the harness from Rambo Marine p/n 508436. $31.30 + $13.95 shipping in July 2012. BTW the green wire is no longer used, believe it used to be connected near the gas cap but actually caused, rather than prevented fires.
