is the j spec cars wiring different from the aus spec? I just wired up my stereo as per tech section and to the pioneer installation and the fronts/rear speakers were wired the wrong way. So I thought the tech section was wrong so I had a look in the service manual. The service manual was different to the tech section. The fronts worked out ok as per service manual but the rears were wrong altogether. I eventually wired them back the right way after alot of stuffing around. Has anyone else had similar problems?
