With the wireless fitting kit you will definitely be able to instal the Blinder yourself.
The point of the WFK is to enable a complete novice with zero expericence of car electrics to fit a jammer quickly and safely.
The main benefits of it being wireless is that you don't have the hassle of any complicated cable runs, you don't have to fit the buzzer behind your dash, and you don't have to put holes in your dahs for the LED and toggle switch.
(as an aside this makes it great for lease cars as you can remove the wireless jammer really quickly and there are no sign left at all.)
The WFK also includes a little power gizmo that you attach directly to the car battery terminals. It works 99% of cars and it only turns on the jammer when you start your engine up. Turn off your engine it it cuts power to your battery. It keeps the battery protected from running flat and it means you don't have to worry about finding somewhere safe to cut into your car electrics for power.
When you're doing it - if you have any questions just post on here or PM me and I'll help.
Good luck and let me know how you get on.
P.S. if this is your first jammer, be prepared for the adrenelin buzz when you first encounter a lidar gun for real. (or maybe that's just me!)
