You need to keep the stock oil sensor and the speedometer (or figure out a way to generate a compatible speed signal for the ECU).
The coolant sensors are detailed in a number of posts here, try searching "coolant sensor location"... the ECU sensor is the one which must remain.
There is no MAP sensor on the 7M, just the KVAFM. The boost sensor is not used by anything but the boost gauge; It does not supply any info to the ECU.
I'll let someone else chime in with the rest. Good luck!
