Zelaya Posted October 26, 2009 Report Share Posted October 26, 2009 Hi guys, I just bought a pioneer rear camera for my Z3 and the only wiring I see is a brown single RCA alone with a red and black cable. Do I need to install an additional cable for my reverse? Does anyone has a DIY instruction. Quote Link to post Share on other sites
Nerds 2 You Posted October 26, 2009 Report Share Posted October 26, 2009 The reverse signal is on the wiring harness for your Z3 Violet/white (REVERSEGEAR SIGNAL INPUT) This is connected so that the navigation system can detect whether the vehicle is moving forwards or backwards. Connect the violet/white lead to the lead whose voltage changes when the shift lever is put in reverse. Unless connected, the sensor may not detect your vehicle traveling forward/backward properly, and thus the position of your vehicle detected by the sensor may be misaligned from the actual position. The red and black wires are to power the camera itself. Connect black to ground and the red to either Accessory switched +12V or to the +12 power at the reverse lamp so it only turns on in reverse. The brown wire goes to the RCA input on the Z3 (also brown) The Violet/White wire as stated above automatically switches the Z3 to rear view camera mode when it receives a signal (when you put it in reverse.)

Zelaya Posted October 26, 2009 Author Report Share Posted October 26, 2009 Thanks for the info, however my Z3 is already installed with nav and working properly. I'm just addinginto the system the pioneer rear camera and inside the box the only wire hardness it has it's only the red, black and the brown single RCA, so that should work right?

Nerds 2 You Posted November 5, 2009 Report Share Posted November 5, 2009 I understood your first post completely and provided the instructions that i did with a purpose. Yes it will work, but if you want the camera to turn on automatically you MUST connect the Violet/White wire from the Z3 to any wire in your vehicle that changes to 12+ or to ground when your vehicle goes in reverse. That wire signals your Z3 to go into "rear view camera mode" so you don't have to fiddle with a bunch of buttons every time you put the car into reverse. You will be able to tell if your Violet/White wire is already hooked up if the screen goes black (prior to camera install) every time you go into reverse. Quote Link to post Share on other sites
