Rear lightning cable color question

[DaanV]

Hi all,

I've tried looking for it but didnt find what i was looking for in this forum. 

In short, I'm trying to hook up a rear view camera and to do so I'd like (as posted before in some how-to topics) to hook up my cables to my rear/reverse lights. However, the color coding of my opel astra 1.7 CDTI 2012 is different from what I was able to find on other posts on this forum. The left reverse light box (which contains reverse and brake lights) have a yellow, black and purple/white cable (see attached picture). Can anyone help me which ones i need to connect to my red and black cables that come from the reverse camera?

thanks in advance, 

Daan

Hi, I wouldn't recommend doing it there your far better of doing inside the car.

Although looking on TIS you should still have green/white.

It's in pin1 of the plug on the light.

Hi Rusty,

thanks for the comment. Apparently the green/white cable that is referred to in several how-to's is coming from the right side reverse light in my car, the yellow/white cable is for the left side reverse light and on both sides theres a purple/grey cable (I presume for the brake lights?). 

Regardless, I think I found the cable in my trunk fuse panel box. I linked to two pictures that correspond to a how-to post from 2017 describing how to set up reverse sensors. Here, a user by the name of Mart showed a picture of the exact same cables that he used to hook up his reverse sensors to (link to post: https://www.vxoc.org.uk/forum/Thread-How...9#pid41619). 

I just would like to ask if you by any chance have an idea if the cable indicated with the green arrow in the picture is the same cable Mart is talking about. The cable pointed at with the Red arrow is more of a geen/grey color and also a bit thinner. Down in the comments of the thread i linked above a user (named Doughy) mentions the thicker green/white cable is the correct one. 

The main worry I have is hooking up the camera to the wrong cable and possibly causing some kind of damage. From all the posts I understand that I have to hook up the red, positive, wire to this reverse lights and the black, negative, to the car body...

thanks in advance for any advice/comments

the pictures in question, where the first one is an overview of the trunk fusebox panel with all the cables, encircled is the cable tree mentioned in Mart's post. The second picture is the individual cables with the two green/white green/grey cables I'm trying to distinguish from each other: https://imgur.com/a/r1rl07r

Did i do something wrong? why is my post not showing?

Reverse light gets power from the BCM, what wire colour is in pin1 on the light that will tell what wire colour they have used on your car.

Failing that you can run upto the BCM and splice into the wire there.


No you did nothing wrong as it states at the top your first 2 posts have to be approved.

So I would like to reply to this topic to say i have installed the rearview camera successfully. Turns out that indeed the Green/White cable in that area was the correct one. Thanks for all the help.
