I think you mean a " Diagram " I think if you would go to your local auto parts store they could give you one or look it up on your computer. They also have manuals you can buy for your car.

Check fuses

pull distributor cap and rotor make sure to mark any plug wires disconnected the pickup will be a roughly 3 inch long curved box looking thing with plug ins on both sides recommend unplugging before unbolting should have two mounting bolts pull old install new in reverse

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".

Fuel supply, check the fuel filter

Check wire that goes to compressor,should tell you or check AC fuse in fuse box.

if you mean no air is blowing,i'd say your blower motors cooked or heater panel blower switch/or blower resistor may have melted

GROUND OR BRAKE LIGHT SWITCH BEHIND BRAKE PEDAL.

could be the starter motor solenoid is stuck the click can be the the ignition relay and the hum is the fuel pump. sometimes works if you hit the solenoid with the a hammer then try to start the engine if this work then change the starter motor or have it fixed.

There are four bolts on each side of the frame mount bumber mounts are and a few behind each headlight and twoninseide the fender on eachside near front top and bottom and it pulles right off make sure you unplug the lights

If the relay is getting no power that's the problem. There are 2 sets of power going to this relay, the control signal (the power that comes from the switch on the dashboard turning on the relay), the second is the much greater power supp[lied to the blower motor itself. You need to test using a multimeter, the relay base to see if you have both signals there.

Check your fuses it might say instrument panel

OK, have you checked your fuses?

the gas line ibeaten the filter and the pump is plugged or pump isn't getting pawer

First try replacing the wiper relay which will be found under the hood in the high amp fuse box. If that doesn't correct the problem you may have a bad wiper switch.

its under powered, do a tune-up and it will be fine. plugs wires cap and rotor

copy and past this link I think this is what you are looking for

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.
