Aftermarket radio harness
I have a 2007 Mazda b4000 SE with the factory radio with cd player. I want to put in my Clarion radio , I have the dash kit but I noticed that there is 2 wiring harnesses coming out of the factory radio. I had put my Clarion in my other Mazda that I had it only used 1 harness and the different websites that I've gone to only list 1 harness to replace the radio. Can anyone give me some direction?
