I purchased this to use with my compustar 4900s remote start on a 2003 oldsmobile bravada. This worked fantastic! This made the remote start install much faster! It actually eliminates the need to connect at least 6-10 wires that you would otherwise have to for your remote start keyless entry to function properly. What a great product, I am going to put a remote start in a friends car soon and I will definitely be using another one. I would definitely recommend this to anyone looking to simplify your remote start/keyless entry install.
