I did it in my old car and Im about to do it again. As long as your clip came with an uncut wiring harness it is pretty straight forward there are just a couple of conectors that you have to swap over from your na harness. There are pretty detailed write ups on this site http://www.mrtwo.net/mr2modproject/mr2modproject.htm . Everything I needed to know about the swap was all on that site. Good luck man!
