Stereo & Electronics - Properly Removing ALL wiring for remote start/keyless Entry

I got my car with a remote start / key less entry /alarm unit few years ago and the system is on its way out.

I wanted to know what wiring is there besides the brain and wiring in area under the steering wheel panel?

Are these wires extended to the door panels for the door lock relays or will these be under steering wheel panel area also?

Thanks

If I am not mistaken, most of the wires will be under the dash not in the door panels. Just be careful when pulling these systems out alot of places install them differently. Some places will cut wires and bypass factory alarm systems so you may have to rewire the factory alarm for the door locks to continue working, some places just tap into existing wiring. Good luck!
