G4 Adapter for 94-95 stuff

This is for GM memcal-to-chip adaptation where you have the little blue 'box' memcal that has the integrated knock sensing board. Those little puppies are a real pain to hack apart, and this adapter makes it MUCH easier. Typically used on ECMs like the 16183247 and that sort of thing (Grand Am, Grand Prix, etc). Chip (C2 27SF512) sold separately.
