This is the stock wiring. Sometimes you need a conversion wiring harness to whatever aftermarket radio you are fitting. Crutchfield does them. The first this to try is bench testing the radio, with power, ground and one speaker, especially if it is not new.

I'm sorry to hear about the fire in your car. Here is a wiring diagram for the 1994 Buick Century with the light bar:
https://www.dropbox.com/s/lbgq6z9e6izb4gc/1994%20Buick%20Century%20Light%20Bar%20Wiring%20Diagram.pdf?dl=0
The diagram shows the wiring connections for the light bar, including the wires for the left and right turn signals, the brake lights, and the running lights.
Please note that this is a generic wiring diagram and your car may have slightly different wiring connections. Also, if there was fire damage to the wiring harness, it is important to have a qualified mechanic inspect and repair the damage before attempting to use the car.

If you have a dodge dealer close to you they will print out a wiring diagram for you.

ok i found a picture diagram for what looks like to be your harness but i you need to get the numbers off the wireing harness its self
these can be very helpful in locating the proper diagram and wireing instructions for this harness
now the pictures and color codes is on a picture at bottom of the link i put in here so hope the link helps youll have to zoom the pic
there is two types of harnesses with the four points (meaning ends)
one is for the clutch and one is for back panel behind steering wheel the guages red is always hot red and black striped is key accessorie hot
yellow is usually the on position once key starts to engage blades or clutch
the blacks are grounds
need a good pic of this harness with out hand in way and closer but showing all the end points ive worked on these but i would rather see it better with more pics if possible

check chiltons manuals, they usually have wiring diagrams in the back of them to show you all you need. its hard to find online ones. you always have to pay for those ones

I've done several of these swaps that sound good at the time but end up being a Huge problem.I would start with the correct harness for the engine you've put in.It must include the under hood harness and what ever harness connects to it thru the firewall to the computer.You'll also need everything connected to the transmission to the computer including any thing connected with the brake and accelerator pedals.Next get the wiring diagrams from Jeep or buy the Chilton or Haynes manual,they have the diagrams included.Get the harnesses connected to the engine,trans and computer,then work backward towards hooking up everything else.I really feel your pain,I've put 20 year newer engines in older cars,V-8's where 6's were,an olds V-8 where a in-line six was(ford),Late model v-8 in a 59' Chevy.All these were simple compared to what your going thru.Please contact me if I can be of any help?

are you talking about the wires that connect the car harness to the gauge cluster with the 2 big plugs?
