Custom FCD Help
Well the fcd is ready to be installed. 1 problem though, the DIY has a different looking plug then the one in my Pressure sensor!!
From the looks of it, it is missing the 12v plug and the wire colors are totally different, not to mention a green plug next to the pressure sensor plug. Plz help, i have a t2 rx7 89

S4 MAP sensors have both 12V and 5V feeds to them, but the S5 MAP sensor only gets 5V. You can use the DIY FCD exactly as per Paul Stoaks' instructions but you have to run a seperate 12V feed to the FCD instead of tapping into the MAP sensor harness. You'll need to measure the voltages at the plug to identify the wires, or refer to the FSM wiring diagrams for the plug pin-out info.
Better yet, install the FCD at the ECU. It's a far nicer environment for sensitive electronics and all connections are easily made straight the ECU's wiring.
