2004 Tacoma Fuel sending unit wiring

Hello, I recently purchased an 04 tacoma trd. The fuel gauge doesnt work. I removed the box for some rust repair and had easy access to the sending unit. I noticed the heavier blue and white/black wires were resoldered to the terminals for the fuel pump (appears to have burned up and was repaired) but the other 3 wires, gray, brown and cream/black were pulled out of the plug and laying there Not connected. The plug is burned and I can't tell which wire used to go where. All 5 wires are Brown on the new pigtail I ordered. Hoping someone knows which wire goes to which port. Thanks
