What do u do with the auto shifter slider thing? when i unplug it my car wont start.

 

that slider things is what the autoshifter used to use but since you did the conversion your gonna have to plug that slider back in. your car will think its in drive and wont let you start your cars, you have to make sure your slider is in the park position. and also make sure you safty switch is down otherwise you will not be able to remove your key.
