Does anyone know the pin asignments for the 20pin connector that the RCA outlets and wired remote plug into on a N2? This connector did not come with my unit and I'm trying to hook up the steering wheel controler and would like to also do the bypass. Didn't want to spend the $70 that pioneer wants for the "system extension cable" if I'm not using the RCA connectors anyway. Thanks, MX5er

Sorry for any mistakes, first time. I have searched alot of the post to see if I could find the info I'm looking for, but have had no luck. I have a 2006 Mazda MX5 -Miata w/o Bose system. I'm trying to install an AVIC-N2 Could use some help locating the best spot to connect to the VSS. Also, I purchased a PESWIPS universal Steering wheel control, appairs to be to be the same as the PAC SWI-PS. There is NO place to plug the jack into the back of the head unit. Am I missing something? I see that there is an "system extension connetctor" listed in the manual that I do not have, and it appear
