Welcome to the fold and congrats on acquiring the fast red FJ.
The MC Cruise is the bee's knees! Though some consider it a difficult install, the kit is very well documented and works great once completed. Highly recommend!! I lucked out and bought mine from another user that may have been intimidated by the install, for a reduced price.
Check this site for other's experiences with the install, and if you decide to get one, read through the instructions several times and set aside 2-3 evenings to complete it. There are also several youtube videos regarding the install and calibration steps.
