Removing qualcomm and tracking system from 2003 Volvo

I am in the process of removing this from outside of my truck, I cut the plug off the end of the wires so I could thread it down the back of the cab, now I am getting a code...not sure what it is...does anyone have a clue?

 

Not going to need it and tired of washing around it.

 

It is not a company truck, it is my truck...the code is a symbol that sort of looks like a man seated wearing a seatbelt with an octagon shape in front of him

 

Any idea where these would be located in the fuse box? The reason I thought it safe to go ahead and remove this, is that when having a/c work done we noticed that alot of the wire had already been cut under the dash, so I was just going to go ahead and take it off. After cutting wires I noticed that the gauges would not work after cranking, so I spread the wires apart where I cut it, then the gauges would work but the code came up

 

Thanks Bid Dukee that makes alot of sense.
