Are there any other recommendations for wiring harnesses in order to change my pcm 2.1 to an aftermarket radio that works with the MOST system (other than most hur). Any help would be great.

 

Im running a Pioneer AVIC-130 double din screen and it is an amazing system; my tech told me he added a module so we did not have to rewire fiber-optics. Im not sure which module he used exactly but let it be known that my aftermarket system is flawless and I have no complaints- Awesome mod..
