all 2nd gens and some early 3rd gens had either a engine mounted pump or a filter housing mounted pump, but to help fix the overheating of the pumps and make life easier, they made a retrofit kit to put it in the tank, thus keeping it cooler and its easier to pull the fuel instead of pulling it.
The 4 wires are used for the stock fuel sending unit, the retrofit kit, and also on the gasser models they have the intank fuel pump also so its a one size fits all since its cheaper to do it that way.
