I bought a new fuel pump. Did not come with very clear instructions. My truck harness has the following colors, large green, black, purple, gray. New pump wire harness has org/blk, gray, purple, black. I am at a loss as what goes where.

Hi,

That's a tough one for me to answer. Did it come with a wiring schematic or anything that indicates what each of their wire colors is for?

I attached the connector schematic below that should be on your vehicle, but the colors are different than what you mentioned. Take a look at the pic below.

Also, let me know if they provided any information on their wiring.

Take care,

joe
