Hi guys!

I recently bought a 2005 Mazda 3 (1.6L petrol engine) which came with central locking through key but not with keyless entry and I want to add an aftermarket solution to the car.
I am struggling to find the correct wires to hook up the aftermarket keyless entry unit.
So far I managed to track down that the big orange connector under the PJB handles the central locking (and maybe other things)
Does anyone have any advices or wiring diagrams that could help me get this little project done?

If needed I can provide you wiring diagrams of the aftermarket keyless entry unit I want to install in the car.
