In the middle of swapping engines

and noticed that the connections for the carb. is different on the new motor (existing is a 93, "new" used motor is supposedly a 93). These are the 1.0 liter 3 cyl. no air base metro. The new motor (purchased a long block with manifolds and carb) has a two wire connector under the carb. on the front side of the manifold (towards the timing chain) that the old manifold did not have, and the connector for the I assume automatic choke on the old motor was a two wire plug, and the new one is a larger four wire plug. What gives? I guess I could change out the carbs. but I wanted to use the new one.

Well, they're "throttle body injection", not carbs. They may look like a carb, but they're fuel injected, and there's no choke. That thing you see is a throttle position sensor. Just swap out the throttle body. Don't take the TPS off, you'll lose your mind trying to re-calibrate it. .01 inches will make the TPS read completely wrong, and drive your engine computer nuts.
