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.

It isn't possible, you have to fix the problem, not find a way around it. The anti-theft system is there to stop exactly what you are trying to do. https://www.fixya.com/cars/r29887709-gm_passlock_security_system https://www.google.com/search?q=bypass+the+anti-theft+system+on+my+2003+Buick+century Videos say you can't but no.

No Vince The most likely is that someone tried to break into it and it is the alarm. Horn pads don't self activate. I guess it might be a faulty relay? https://www.google.com/search?q=2000+Buick+Century+Custom+horn+went+off+on+its+own ..

This is the bolt, but the answer is the size of the socket that fits it. If you don't have a full set of sockets and wrenches, doing job is impossible. If it is oversize, and I don't think it is, you can get larger specialized tool from Autozone for free and just a small returnable deposit. https://www.google.com/search?q=2001+Buick+Century+Custom+harmonic+balancer+bolt ..

Question edited for clarity. Question moved to model category. Check where the earth from those lights meets the bodywork. It is a known issue https://www.google.com/search?q=2003+Buick+Century.+My+license+plate+bulb+not+working

The Buick Century uses separate relays for the hazard warning and turn signal functions. The turn signal relay is located on the accelerator pedal bracket, and the 4-way flasher relay is located on the convenience center near the left kick panel. Try switching these two relays with one another to see if your turn signals work instead of your 4-ways.

it's connected to throttle body you have to remove it to change thermostat V6 3.3

I have been in the business for 35 years and have never seen a "brake line diagram". You easiest way to figure out which one goes to the right front would be to start at the right front caliper and follow it to the hydraulic control module.

Start by having someone press the horn while you feel the relay with your finger. If the relay clicks when the horn is pressed then the switch is working properly and your problem is between the relay and horn assembly.
