SE Drive Smart 450

[Jomac]

I am working on a conversion system for changing gears that does not require any programming of the SAM or any other unit in the car. I have used Jaguar XF gear paddle switches which are easy to mount. The gear up and down is transmitted using a small radio module and the receiver will connect to the original SE Drive PCB. I have designed a small logic board that connects between the receiver and the SE Drive PCB which switches and routes the signals correctly when changing gears, the logic fools the SE Drive into thinking you are changing gears on the gear lever and not on the steering wheel. I am after the full circuit so I can see if there is an easier way to interface the receiver and the logic interface board.
