I have a 2001 chevy tahoe. if i purchase the compustar 7900as, what else would l need to purchase? do i need the idatalink blade?

I just bought this one and yes I also bought the blade and idatalink ALCA databus interfuse. Getting mine installed soon know for sure I'm going to need them cause the installer might not have them.

Does this include everything to put into a car?

If you don’t need an immobilizer bypass then yes. If you need one then no. You can seriously damage your vehicle electrical system if you don’t do this correctly.

Would this work as is on a 2015 subaru forester xt? Do i absolutely need the blade-al?

This is a universal kit, however, the programming will require the blade-al for 99% of it's applications. You will also need the USB cable ($30) on Amazon to transfer the program file from the website.

Would this be easy to install if i never installed one before?

You need to look up your vehicles wire diagram and splice into a lot of wires to get this installed. Also if you have chipped keys, like in newer vehicles you'll need to buy the BLADE piece as well. The BLADE is whats called an Immobilizer bypass. Meaning is mimics your chip in your key so the car thinks your key is close to it, so it can remote start.
