my stock fuel pump only have 1 wire harness and the new fuel pump I ordered have 2 wire harness plug ins at the top of the pump. What should I do
 


That missing plug in your first picture is a fuel tank pressure sensor used for you evap/emisions..any 97 and up wbody should have it
 


Should be there. Post a pic of your actual pump not a googled one so we can see what is going on...some aftermarket pumps have you move that sensor from your old pump to the new pump. Maybe the prior owner of the car put a new pump in and did not do that..stick your hand in that opening the wire harnass may be sitting on top of tank not hooked up. It's your ses light on?
