    I dropped my fuel tank and busted the wire harness off of my fuel pump, does anyone know the color code for the 5pin wire harness on a 2013 tundra 5.7l flexfuel ? The Toyota shop doesn’t seem to know or they don’t want to deal with me.

    I did the same thing. I got the blue and red back in the harness enough to run but I completely broke the sending unit wires. I'm planning to do some junk yard surfing tomorrow to see if I can find one to splice in. If I get one I'll post a pic. I can tell you that the blue and red go in the row with only two ports. The blue goes to driver's side. Not sure which way the sending unit wires go. But it's just a resistor so trial and error will suffice. It might work either way actually but don't quote me on that.

    I did the same but the red and blue wires came completely out. On my 2013 Tundra pin 1 is a NC with a blue plug. Pin 2 is yellow-green. Pin 3 is green.
    I don't know the correct color for 4 and 5 (red,blue). Does anyone have that info? The numbers are on top of the connector and are hard to see.
