Removing an aftermarket alarm

Hey everyone. I have scoured other posts and the wiring diagrams. I am having issues removing a troublesome aftermarket alarm from my 07. The dilemma I'm now having it figuring out where this brown wire goes. The truck will run now but the dash will blink, click and trigger the 4 ways. The high beam are also disabled. Someone help! It comes out above the parking brake and runs up near the steering wheel then back into a bundle of wires that leads into the firewall.

 

Hello. I was curious if you ever figured it out. I just bought an 05 DC and it too looks like it has an aftermarket tornado. I am just getting started on figuring out what everything is any tips or direction would be appreciated.

 

You need to put the red/yellow back together, undo those taps and get that relay out of there. If you are looking to remove that thing.
