[Help] Reverse camera wiring

[Medic-one]

So i've bought this double din radio satnav bluetooth etc unit (Eonon G2240) which also comes with a reverse camera, but i've not really got a lot of experience with wiring things in so struggling with this a little bit.

This is the unit from the back :



I found this picture about the camera online :




But mine is slightly different as it seems to have 2 wires comes out of it, instead of one.



The camera has a black and a red wire coming out of it.

The black wire fits into another black wire, that ends in the big yellow plug (that goes into the head unit) and a thin red wire.

The red wire goes into a red plug, which ends in a thin red and thin black wire.


So i'm thinking :

1) Big yellow plug goes into the head unit at 'video in' port 17.

2) the little red one that's with the yellow plug, and called 'reverse image trigger line', i using a crimping tool to connect it to wire number 7 coming out of the head unit labelled 'reverse control'.

3) Then using the red plug ending in the thin red and black wires, i crimp the red wire into a 12v power supply. The actual connection harness allready has an extra power suply crimped in for my AFR gauge, and this has a free port :



That i crimp that thin red wire into the free red plug.

4) And then i'm suppost to do something with the thin black cable...


I'm not sure about step 2, 3 and 4, so any advice welcome

I will guess that the thin red crimps into the reverse light circuit and black goes to ground.

So when reverse is engaged power is fed to the camera which sends video signal to yellow and triggers head unit to switch input based on the other red?

^^^^^ What he said.

Spot on, I have fitted a similar unit a year or so ago & this is what I had to do.
