Cavalier Engine Swap Help!!!!

i bought a 2000 z24, i spun the bearing, bought a 98 z24 (crashed so was cheap), i pulled the engine and found out that was already swapped from a 97 Grand am....the engines look almost identical except for the EGR valve thing....but ok right now ive got the 97 grand am motor in my 2000 cav body, its already attached to tranny and all mounts are on, but some of the wires from the body dont seem to match up, maybe im doing them wrong or are these motors different?
