Mine came with both the MAFia and a harness extension. I went ahead and soldered everything in.
My Procharger book had instructions for the MAFia but it wasn't included. Sorry to hijack the thread...my instruction book might as well have been left out, it was almost useless. I just tried to make my life easier, like I was to the OP for his MAF extension
