Default Engine wiring harness

Hello need some help please, i pulled out the engine from my 97 trans am, 6speed, i installed another engine from a 97 firebird formula automatic, and now i cannot find the connector that goes to the distributor any particular place i should look for it because i cant find it in the wiring harness. Also my old engine has a "sensor" at the bottom of the timing chain cover and the engine i installed doesnt, whats that about? Does it really need it, or can i just leave the conection alone???? Thanks.

sensor at the bottom of the timing chain cover is the crank sensor. car will not run without the crank sensor. plugin for the opti is on the passenger side intake harness. look here http://www.shbox.com/1/evap_sol.jpg

Thank you found it, few more questions if you dont mind, is there supposed to be 2 EVAP canister purge solenoid valves? I have one on the right side of the intake, is there supposed to be another one close to the air pump? I ask cause i have 2 of them, but i cant remember if one came with the engine i put in and it might be extra? Also, where does the vacuum bleed valve connect?
