2003 4.3v6 6.0 swap

Ah, didn't read it that way. Yeah, must be the alternator plug. :thumb: Good call.

After looking over the wiring I am going to take a guess and say that the oil sending unit from the 6.0 will not work with the 5.3 harness?

It seems the oil sending unit from the 5.3l has only one wire, the one on the 6.0l has three wires?


Also it seems the fuel rail system from the 6.0L is a return less system? What is going to be my best option for making my 4.3 fuel system work?

i cut my fuel lines and ran fuel hose to make it work, the oil sending unit i just replaced it with with a 6.0 sending unit from the parts store.. or just take the 5.3 sending unit and install it on the 6.0

So are you saying you just cut the fuel line and spliced a T in? I am thinking of just finding a fuel rail from a vehicle with a return system.

Im sure you saw my threads, but I shortned up the stock fuel hose with a small pipe cutter, then ran some AN fittings as well as some steel braided hose. Works great
