To answer your question is that yes it will work. You will have to buy an adapter from your harness to the new style 4 or 6 pin.
One thing to look at, is the maf's diameter too big for your blow through application? If it is, you will have airflow problems around the maf sample tube. I used a maf out of a Mach 1. Has the same diameter as my inlet tubing so there was no turbulence through the sample tube.
Also, not sure if 42#'s is enough injector to get you where you want to be safely. Consider getting 60#'ers, and recalibrating the maf for that.
