Fuelpump wires

[Jense30]

hey guys,

a friend of mine have a little challenge. He bought a unfinished tracktool and we have 2 Problems with the wiring harness.

The Car (Original 318i NFL) had a Fuelpumpe on the outside, now its changend to inside but the wires are still stock.

First Problem: The marking say that this should be the fuelpump...



...but that makes no scene because it looks like this (random demo picture)



so now ...wtf is wrong?

and because its not getting boring we have some other cable that we also dont know were to go with. Do we need them?



Would be great if someone can help me.....and yes sry for my poor english :(

Best Regards
Jens

The car is wired for a lift pump in the tank. Pic 2.
The car is wired for an external main pump, pic 3. this sub harness should pass through the body to the niche just ahead of the left rear road wheel.
warning: the fuel pump circuit may have been modified.
