It'll fire up and run alright so long as it's not security. Security will need a bit more than just the engine harness and it seems like it's the fingerprint circular key that's security.
If there's cycle issues going down the road a tuner could straighten them out though the CEL may stay on/tripped. I mentioned the van PCM as that may be an inexpensive alternative if there are cyclic issues going down the road and I usually bring it up since they have the 3spds in them with the bell already clearanced for the CPS and all.
