I have a 2002 honda odyssey. I recently purchased a Z3. I was wondering where do i connect the pink wire(car speed signal input) on the ecu. I need to know the color of the wire in the ecu where i need to connect it. or can i connect it behind the speedometer and if so what color is that wire.

blue/white wire at the PCM.

The PCM is located in the center console. The speed sense is located in a 32-pin plug.
