Default Looking to buy an HFS-4, Question on configuration?
Hi,

I'm looking to buy the HFS-4 for my 2007 Mazdaspeed 3. I have to choose between two different vendors. My question is are the HFS-4's universal other than using the diagram for my specific car or does the unit need to be modified (soldered) to work with my application? Or do I just buy the unit from anyone and just install it? Thanks. Rick
