HELP! Unknown connectors

[Jazic3.4]

I put my 3.4DOHC motor back in the 92 Lumina but it won't turn over? The battery is fully charged. When I turn the key, the main cooling fan relay buzzes like mad and the temp gauge goes to the maximum reading turning on the dummy light which is located right next to the temp gauge??Both fans are connected to the proper wires but I noticed a wire hanging but not sure where it goes. Its hanging right between the oil filter and the cooiling fans. Its female with a light blue weather pack rubber protector. It looks like the picture below. I hope this has something to do with the no turn on problem.

There is also a red single contact female connector coming off of the positive terminal post. Does anyone know where this goes??

The single red one is nothing. It is like a Fuel Pump Test Lead or somethign. Doesn't coneect to anything. The other one sounds like one of the connectors that goes to the ICM.
