You don't NEED a 5 pin box. 4 pin will work in place of 5 regardless of whether you have a 2 or 4 pin ballast. But a true 5 pin MUST have a 4 pin ballast
I would SERIOUSLY consider a conversion to a simple 4 pin GM module. They are in effect, a 4 pin box, and many of us use them. I've used these on several conversions, including the now long gone Toyota / Cletrac, "Toyotrac"
