wirring problem

[wroberts20]

i swapped a 92 explorer 4.0 into my 86 B2, i am getting fuel, it turns over, but no fire. i was told the check engine lite must be wired to the new harness to fire, is this true? if some one could tell me what conections they made in their swap it might help if i missed something. i am at a stand still and i miss driving my b2. thanks for any help.
