Hi all,

simple question, I have a mazdaspeed 3 2008 (MPS in oz) with the bose system. is the Metra harness part # 70-7903 the correct harness to use to connect to the stock wiring? I will be splicing RCA cables to the harness so I get line level out from the headunit.

thanks in advance

hmm read post #5, couldn't see anything useful... not too sure what I was meant to be looking for.

Surely there must be people who have bought this harness?
