What color is the fuel pump power wire?

[tsi1991awd]

I'm trying to find out what the fuel pump wire color is that runs along the floor board to the back. I know the plug for the fuel pump is in the trunk area, I unplugged it when I did my fuel filter. But is there a power wire that runs along the drivers side floor board? If so, what color is it in the harness?

Instead of going by color, I would use a multimeter or a test light to determine which wire has 12v. Sometimes car manufactures use different colors for the same wire. Heres a link to a 1g fuel pump re wire which shows what color his was.

^ I think I'd be more inclined to measure resistance than try and measure for 12V. Just use something at the fuel pump end and then trace the wires to where they go under the dash and keep prodding around until you get a blip on the multimeter for resistance.

The power wire for the fuel pump relay, at least in my 2g, is black with blue stripes.

What is the fuel pump rewire for? I know it says voltage drop under WOT....is it for if you have fuel cutoff or?

Perhaps this will help.

The wire is Black/Green for part of the way and they becomes Black/White to the pump.

It's to allow the pump to receive full voltage when it needs it the most.

The smaller gauge factory wire causes a voltage drop when the pump draws current. As the pump works harder the current draw goes up and the voltage falls off causing the pump output to fall off.

Hmmm, guess I should consider doing the rewire then. Thanks for the diagram and clarification.
