This could be two different issues. For the dash light get the vehicle plugged into an OBD scanner or a diagnostic system to check for Trouble Codes. These will give clues as to what and where the issue could be. Comment below with them and I'l try to help explain them.
Unless the problem is with the brake booster most traction control systems do not use a vacuum to operate it. It is usually a set of electronic sensors on the wheels that the ECU uses to monitor tyre grip.
As I cannot look at the car myself for that hose you will need to get a good mechanic to look at it. The vacuum hose could go to many things like the EGR system, the Turbo (if fitted) or possibly to the transmission.
I would suspect the engine management block. Take it to a dealership for specialised repair as electronic parts get destroyed with incorrect polarity.
This will be expensive!
no engine told at all. (i will answer for USA spec, cars only)a Generation 4 car.such an easy problem. any car the fails parked is easy to diagnose and 10x more safe to do. 2 engine, offered day1 new. which one is it.3.3 L V63.8 L V6Ever fix an engine that only fails down hill in left turns only.see?hood up.not told you, does the starter crank the engine fast when dead.?called a no crank engine, or is way too slow ,weak battery.aka. cranks fast but will not start.you have 2 hours to find it, easy no?1: we test for spark first. google how to test spark. 100 years its the same way..do not ever scramble the 6 wire coil pack wires.2: ok spark is good we use spray test fuel (in a can) called instant start in a can, does it start now?yes. but runs 3 seconds and stalls.3: fueling is bad, we just learned. if will not run step 2 that is a bad engine,easy no? just simple tests so far.next comes fuel pressure. test at the fuel rails using fuel pressure test gauge. (a tool) 55 and 49psi chart above order. spec.keep in mind it can be just 1 rusty wire, wrongnot replacing by guess 10 or 20 good parts and now broke.it can also be bad fuel or dead fuel pumpand lots and lots more, but we do the tests in orderto find the cause, and more tests. watch scotty yethttps://youtu.be/064Ilsz8Fzg
You are questioning the answer from full time vehicle electronics technician who does this 5 days a week and is our Fixya vehicle electronics Expert when he isn't. He has access to all the Ford technical bulletins and schematics.
This is a Fixya Tip I put up based on an answer given by Jeff on GM Passlock. Yours is similar but different. If Jeff say it needs programming, it does.

Please update to how you get on. Thanks.

The C0292 code in your 2004 GMC Yukon Denali XL indicates a communication issue between the Powertrain Control Module (PCM) and the Electronic Brake Control Module (EBCM). Here are some steps to diagnose and potentially fix the problem:
Check Ground Connections:
Inspect the ground connections related to the PCM and EBCM.
Follow the ECM ground and ABS module ground.
Check the ground on the firewall (driver's side) and the frame rail under the driver's seat.
Also, verify the engine ground on the driver's side.
Inspect Wiring and Connectors:
Visually examine the wiring harness and connectors associated with the EBCM.
Look for any signs of damage, such as broken wires or corroded pins.
Ensure that the connector pins are not bent or pushed out.
Pay attention to any loose or poor electrical connections.
Consider the Tune:
If you've recently modified the vehicle's tuning, consider reverting to a different tune.
Sometimes, a specific tune can cause communication issues.
If you suspect the tune, contact the tuner for further guidance1.
Professional Diagnosis:
If the above steps don't resolve the issue, it's advisable to seek professional help.
A qualified mechanic can perform a thorough diagnosis using specialized tools.
Keep in mind that diagnostic costs typically range from $75 to $150 per hour.
Yes, I would look closely at the bottom of the lighter socket for any kind of foregn material that might cause a short and then check for a blown fuse and replace if needed.
Take your Rainier out for a drive and see if the cruise control still works. If it does, the VSS is likely fine. If not, the VSS could be the culprit (Vehicle Speed Sensor). Cruise control also depends on throttle position. Ensure that the throttle body and related components are functioning properly. Examine the wiring going to and from the VSS. Look for any damaged or frayed wires.
The most common reasons for cruise control malfunction are failed control modules, faulty sensors, or switch issues. While you've already replaced the brake switch module, it's essential to verify that it's functioning correctly.
Additionally, check other control modules related to the cruise control system. While you've already replaced the brake switch module, there might be a separate cruise control module. Inspect this module for any signs of malfunction.
Powertrain Control Module (PCM): The PCM monitors the signal circuits of the cruise control switches to determine when to capture and maintain the selected vehicle speed. It uses the throttle actuator control (TAC) module motor to control the vehicle speed. That would be something to check. Visually check cable connections and for corrosion. A multimeter can check the battery which can affect the PCM.
Sometimes, disconnecting the battery to clear any fault codes can resolve cruise control issues. Possibly that might work even though you see no fault codes.
OK, more information please. What year is this Bakkie? What engine is in it?
What Exactly does it do when you try to start it?
Nothing at all at the key, just a 'Clunk' or a very lazy turn over suggests a flat or weak battery. Batteries do get old and weak especially if they're over 5 years old or on a bigger size engine. Try putting it on charge overnight and see if that helps.
Does it just spin and not try to start? This could be a 'No Spark' issue.
Does it turn over, try to start then immediately stall? This might be a fuel supply problem.
Dash lights only use a small amount of voltage so they are often the last thing to stop working.
Adding aftermarket radios seldom works like you expect because the radio head and amplifier are connected to, and monitored by the BCM. Safety warnings and door chimes are played by the BCM via the radio system. It was all designed as a seamless unit on a computer network. Phone Crutchfield, they do all the harness kits and will give you good free advice. Or go to a car audio installer, as they have the programming equipment.https://www.google.com/search?q=2003+ford+taurus+wiring+kit+for+the+amplifier..
