05 V70 fuel pump wiring

I finally got my known good fuel pump installed, but no luck, won't run. So now I am checking electrical issues but don't have a wiring diagram. Can anyone tell me color of the power wire to the pump motor? This is a steel tank car with the pump and sensor together on one side.

big blue wire should be 12v feed, black is ground.
watch Ivan work his waY through this no start pump problem.

White black to the pump.

Here’s the 2005 piece of wiring diagram, pump is 6/33. The PEM unit is shown above.

Check the threads to make sure the pump takes 12 volts as it’s PULSE WAVE MODULATED
