I have a 95 century and I am trying to find out how to program keyless entry. From every place I looked online it said the programmer should be a blue connector with nothing in it but all I found was a blue box with letters on both sode and wires leading to most of the lettered holes. Is this it or something else?

There is a connector in the left rear of the trunk that needs to be jumpered. (It will be hidden behind the interior trim panel)
Once you locate the connector and you have the remote key fob(s) in hand, short the two terminals together (you'll know you got it right if all the locks cycle).
Press a single button on the transmitter once (again the locks will cycle).
If you have a second remote fob, again press a single button once and the locks will cycle again.
You're done! Remove the jumper and test the key fobs.

I found a little plastic part with a black and white wore connecting to it coming from alarger coiled wire in the sode of the trunk. Is this it?

In the left side, one wire is Black and the other is Black w/ White Trace.
Jumper those should cycle the locks. Make sure you have all the fobs that are being programmed in your hands and ready with fresh batteries, if possible.
Let us know...

It looks like mine doesn't have one in it. Thanks for the help though. I appreciate it
