Citicar issues - May 28, 2010

My Citicar was delivered today.  It has a few issues.

The first picture shows two ends of the blue wire that may have come apart.
Should I reconnect these ends?
 
Before I got the POP sound and the white smoke (while going forward) I could not go back at all.
Would this have been the cause of the car not wanting to back up, as well as the POP?
 
 
Here is what the blue wire from the solenoid looks like. 
Maybe I should replace this?  Should I use a heavier gauge wire?  What gauge would you suggest?
 

 
Below is that white disconnected wire at the passenger side tail light.  Should I reconnect this?

 

Below is a disconnected wire on the driver's side tail light.
Does this go anywhere?


 
Please call or write me regarding this.

Thanks,
Steve
