we install them at my work (futureshop which is owned by bestbuy)but we dont sell them lol..you have to get a special starter.. one that is ment for 5 speeds. when they install them thay put in a secnsor... if its in 1st it wont start... also they hook it up to the ebrake and if the ebrake is not on...it wont start. but if it is in any other gear but 1 it will try to start. so u have to leave it in nutral.
