HKS PFC F-con help

So i recently acquired a fcon system I wanted to put old school stuff in my so there's the first piece my question is does any one have the pressure sensor and chip that goes for are car it has a 104 in it now that I'm pretty sure goes to a miata it seemed to work fine though when I plugged it in but no pressure sensor so fuel cut under booster. Any help would be great thank you!
