Chevy blazer fuel pump wiring?

i have a 97 chevy blazer. My fuel pump went so i purchased a new one. i did not know that the company changed the wiring on the fuel pump..all the wires are 2gether in the wiring harness and all i have to do is cut off the old harnss and wire the new one in its place. Im not sure exactly how to wire it. What do I do? do i just strip wires and twist them or what?Chevy blazer fuel pump wiring?trace down old wires from pump / sending unit there will be one wire that goes to both the pump and sending unit....... that is ground ....mark old wires before cutting ....... then hook to same on new pump
