Conversion LS1 Harness to Lt1 Fuel Pump

Okay I am in the middle of a lt1--->ls1 swap. What I did was put the complete ls1 harness (yes every wire in the car has been changed) in the lt1 car. Now I am at the point where I have the LS1 harness and the LT1 fuel pump. So I want to splice the LS1 harness into the LT1 harness right where the harness is riveted into the body.

However there are more LS1 wires then LT1 wires? Can anybody tell me how to splice these two harnesses together?

there should be 2 more wires on the LS side due to the tank pressure sensor. I don't remember all the colors but thats why you have more wires.
