I did a search and just came up with people selling their harnesses. I would like to put a 3 or 4 point racing harness in my EF sedan. However, I don't know exactly how these "universal" harnesses install and if I would need to do any kind of modification. Also, will they even be functional with my stock seats?Please give feedback/advice and any pics are more then welcome. Thanx.
