Hello,

Does anyone have/know where to find the wiring diagrams for a 2008 mazda3? I just got an alarm and I don't want to install it with out the diagrams. Mostly I'm looking for a "whats what" list for the steering column.

Thanks a lot

 

Does anyone know why 08 mazda 3 I sedan factory harness aont allow me to hook a amp to it?

 

do you mean why does it not have RCA connections for you to plug into? If so the answer is because it's a factory stereo system and pretty much no factory systems include things to make hooking up aftermarket components easy.

If you want to hook up an amp you need to install a LOC (Line Output Converter). It pulls the signal from your speaker level outputs and converts them into line level which can plug into an amp's input. Alternately there are amps with speaker level inputs.
