Converting a Dodge RAM 1999 RAM fuel pump wiring harness to Dodge RAM 2500 5.9Does anyone have the wiring diagrams for fuel pump harness on these two vehicles I am trying to in a jam use a Dodge 1500 fuel pump although it only has four wires and the original 2500 pump has six. I was hoping to use it until I can afford the a new 2500 pump. The wrecker only had a 1500 so I picked it up for 20 bucks hoping to do a temporary fix

I hope it will work although it may not due to different viscousities of the two fluids. Theres for sure a reason or they would all be the same pump. Will it even fit in the tank, and seal up?

Actually I don't think it will work at all because gasoline fuel injection is roughly 40-50 PSI and the diesel lift pump is only 12-15 PSI even if you did get it to work the pressure would be too much for the VP44.
