Thank you for the kind words gents Hopefully once things are complete it will look pretty OEM in terms of fit and finish, that's the goal at least.
Not much in the way of photographic progress to report of late bit I am achieving some pretty satisfying pieces, really cool to start seeing the engine and car go from two separate things to being somewhat integrated now !!
Wired up transmission so now have functional reverse lights and neutral switch
Wired up ignition on so can use the key to power up engine electrics
Run all cables inside the cabin that need to go there from the back side of the 'secondary' Deutsch 31 pin connector
Planned where the OBD2 connector and Arduino will be mounted
Located wires for oil pressure and alternator lights to the dash
Next up will be finalisation of the wiring inside the car ... fuel pump relay trigger, brake switch, power supply for Arduino, CAN connections, dashboard bits etc etc
