98 3.0 to 4.0 Headlight harness and fuel lines

[Kingoverace]

okay So I dropped in a 97 Exploder 4.0 and trans in my 98 Ranger. The two issues I see right away
1.) The headlight harnesses on the truck does not exactly plug into the headlight harness on the motor. On one the plastic connection block is square, the other is alsmost rectangle. Should I get a new headlight harness and bulbs or take the connection block from another Exploder and run the wires into that?

2.) I see 2 fuel lines coming off the 4.0 and only 1 running from the tank. Did the Exploder have a different setup? Whats the solution?

Headlight harness

Fule lines

well to answer the fuel line question. the explorer has a returned fuel system, well that is for the v8 so i assume it is the same some one else could back me up on this but im pretty sure thats what your seeing on the fuel system your ranger has a returnless fuel system
