Installing 2 way radio difficulty ? Stellar STRS9950

I received this alarm from a friend free, brand new in the box. Wondering how hard it would be to install.

Stellar STRS9950 (2 way), and the RM2000 (2 stage radar motion sensor)

I would also be open to paying someone on the forum who has the knowledge to do this professionally, I remember someone offering alarm installs to members but can't recall who it was.

 

Are you familiar with installing alarms or stereos? Alarms can be really hard to install depending on the alarm. It's easy to screw it up and make your truck not start.

I'd say if you haven't done this before or you are not comfortable with complex installs I'd pay someone to do it.

 

Ive done a basic alarm, but it has been a few years.
