Hi i am installing a reverse camera on my Grand Voyager. I need to connect it via the wiring for the reverse light does anyone have a clue which wire is which in the tail light harness. I am running the power cable from the centre of the tail gate between the parking sensors under the rubber seal to the passenger side tail light and want to connect in to the plug that connects the lights. Hope someone can help its so frustrating this being the only thing stopping me at the minute.

 

Hi there,
Just replied to the same question in another thread!
The easy way is to get a DVM and measure each pin to GND, when selecting Reverse.

But from the manual,

LEFT REAR LAMP ASSEMBLY - BLACK 6 WAY
CAV CIRCUIT FUNCTION
1 L63 18WT/DG (EXCEPT EXPORT) LEFT REAR TURN SIGNAL DRIVER
1 Z363 18BK/DG (EXPORT) GROUND
2 L63 18WT/DG (EXPORT) LEFT REAR TURN SIGNAL DRIVER
3 L50 18WT/TN (DIESEL EXPORT) PRIMARY BRAKE SWITCH SIGNAL
3 L77 18WT/BR (EXCEPT EXPORT) FUSED PARK LAMP RELAY OUTPUT (LEFT)
3 L50 18WT/TN (GAS EXPORT) BRAKE LAMP SWITCH OUTPUT
4 L1 18WT/LG (EXCEPT TRAILER TOW) BACK-UP LAMP FEED
4 L1 18WT/BR (TRAILER TOW) BACK-UP LAMP FEED
5 Z363 18BK/DG (EXCEPT EXPORT) GROUND
5 L38 20WT/YL (EXPORT) REAR FOG LAMP SWITCH OUTPUT

6 L77 18WT/BR (EXPORT) FUSED PARK LAMP RELAY OUTPUT (LEFT)

Thats brilliant thanks ill give it ago now cheers.

 

well that was confusing I have three green wires all the same green, one gray and one yellow any ideas anyone :-(

 

DVM (voltmeter) is your friend. :-)
Select reverse, disconnet the plug from the lights, 1 probe to ground the other probe into the plug to check which one is giving 12v. Simples

 

Hi this is going to sound really stupid but here it goes. I have a voltmeter that was given to me a couple of years ago but I have no idea how to use it I don't know what setting to put it on and do I use the positive lead on the plug and what does ground it mean. I take once I have found the live wire it will show 12v. how do I find which one the negative wire connects to as my camera has a black and a red wire. See did warn you it will sound really stupid. LOL

 

No worries,
there should be a black wire in the plug which is the ground / negative.
If you look at the actual light cluster, you will see that each blub is connected to one another via the metalic strips, to this single wire.

Your voltmeter probably has a couple of options to select the range ie 2v, 20v, 200v. You just need to select something larger than what you are measuring. anything less than 12V will be useless.

So in short. Select reverse, Black probe to black wire in plug & with the red probe you can try each wire in the plug. Providing you have no other lights on, only one of them will read 12V.

Then just connect your camera to these wires. I can provide pics of mine you want.
