Need some direction

[jmcald]

Hello I am an owner of a 2001 ram dodge. I have been having problems since like 6 months ago. I'm hoping someone can guide me on to what might be the cause of the current problem I have. In the most short and concise explanation is this.

What is wrong:
Has abs light, check engine, breaks, and air bags
Air conditioner and odomet is not working.

What i have fixed/changed :
Transmission speed sensors
Back abs sensor
And a couple of wires that where frayed (soldered them they were above the transmission)

My question is what can be wrong. I have tried and replaced what I can for the knowledge I have but i need help. I think that some of the fuses are not working because of the wires that were frayed. But how do I know which ones are good or bad? If anyone has some helpful input I would gladly appreciate. Yall enjoy yalls rams

But how do I know which ones are good or bad?

Pull the fuses and see if any are blown. It is very easy to tell the difference.

Might be a dumb question, but...does your truck actually run?

My truck has tripped every light on the cluster plus inoperable gauges for two reasons over the years: 1. faulty timer module, truck still ran and drove, and 2. bad ECU main ground, engine would crank but not start.

Otherwise, I've also seen a few cases where vehicles suddenly trip every light on the gauge cluster and lose all gauge function but still continue to run. Each of those was the result of a bad alternator and the battery slowly running out of power while the vehicle was running.
