Default KJ-66 Tach and EGT

Can someone please guide me as to how I go about fitting a Tach sensor and an EGT to my KJ-66 so I have signals for the ECU ? I can build and wire basic boards and circuits but I don't where to get the info on this. Any help would be much appreciated!

Mine used to be optical.
An infrared diode on one side of the intake shining through a cross drilled hole in the compressor nut and onto a receiver at the other side of the intake.

EGT is just a thermocouple sticking a few mm into the exhaust nozzle.
