Without a little detail. Il gonna guess thats the main bulkhead connector at the firewall? As shocking as it may sound, alot of cars have alot of wire harnesses with large groups of wires, and they mostly all look similar.
When you say its the problem, that leaves a large amount of gray area. If it IS in fact the problem, then the nature of the fault determines the proper repair. if the connections are green or rotted from water intrusion, depending on damage level it might simply need a good cleaning (disconnected, both sides male and female) and perhaps retension the pins and it would be fine. IF that is all that is wrong.
If you have a burned wire(s) issue, then the bu8rn that happened at that connector may be caused by poor insulation in that connector, or it could be a short somewhere else that had high resistance at that connector (loose or dirty contacts as described above) and that connector simply melted from the excess heat/amperage...but the original cause may be inches or feet away from the connector.
Wiring is one of the most poorly serviced areas of modern cars. Nobody generally pays it any attention till there is a failure, and when that happens, often a problem that started in 1 small spot has spread,, or damaged other components and will require significantly more time to repair and determine original cause to prevent it from failing again.
a better description of the perceived fault would be helpful, and the symptoms including how often, conditions leading to its first occurance (if any) and why you believe that connector is "The problem".

I don't know if you fixed your problem yet but the fusible links will be near the altenator. They are should be black in color and an inch or so long. They will be on the positive lead(s). Have you tried starting the car by jumping solenoid on the starter to see if the starter even attempts to engage?

I have a 1990 Chevy Caprice. I just put a new starter on it and now the whole car wont start. the lights wont come on or anything. I charged the battery but nothing happened.

I would make absolutely sure that I did not hook the battery up backwards, not uncommon.
And in addition to the high current thick cable from the positive terminal to the starter there
is the small connector to the relay on top. Easy to forget that also.

If you hooked the battery up backwards you now need another car as the wiring harness is cooked.

Chevy caprice doesn't start. Turns over but, no start.

Check spark. Is this one of those with the HEI coil on top of distributor? Check the ignition module in the distributor under the cap and rotor.

well the running rough part sounds like a fuel pressure regulator..and as far as the smoke goes there could be a puddle of it somewhere on the motor so it spills a little at a time causeing it to smoke for a while or your oil filter could be loose and that would cause it to leak so maybie ckeck your once in a while to see if it loses oil or anything like that.
