ok i swear all 4 wires on my pump harness are black.



are the 2 wires that go to the negative terminal on the pump the negatives and the other two are the positives?



this is really confusing now for some reason. i had two wires going to the pump negative, one to the pump positive and then one to the top of the sender level thing, or whatever it is, mounting location.



what wires do i connect to each other to wire up this walbro?



kevin.

upon closer inspection (i removed the heat shrink tube).



One wire from connector goes to + side of pump, one wire from connector goes to - side of pump, one wire then goes from- side of pump to grounding by the level sender unit thingamajig.



kevin.

There are 2 ground wires, 1 power wire, and one wire the goes to fuel level sender. Just follow the wires from the pump. On the pump there's a + and - marking.

yea i just threw away the one from the negative to sender, and wired the walbro harness into the correct + and -



runs like a champ.
