You need a pressure sensor and a wideband sensor+controller. Wiring isn't too bad.
The fuel pressure sensor has three wires. One connects to 5V+ (there's a wire on the MAP sensor you can use), one connects to ground and the other connects to dash logic
For the wideband you have to install an additional O2 sensor then run the wire for the sensor back to a controller. The controller will need 12V and ground, and will have an output wire (0-5V) that connects to the input on dash logic.
Then you have to configure dash logic to know what to do with the signals it is now getting
Not hard by any means but takes some time to do it neatly.
I'm using a PLX gen 4 4.9 wideband and for pressure sensor Honeywell's PX2AF1XX150PSAAX should work. It has a female schraeder connection so it will screw on to the end of the fuel rail.
