Reverse camera to aftermarket head unit

[Goose89]

Hi everyone, thank you for the add, first post. 

I have searched for this and not found any specific information.

 

Does anyone know if the JDM Fielder NRE161G reverse camera has a 4pin connector at the stereo end? and whether it runs on 6V or 12V?

 

Wanting to connect OEM reverse camera to my aftermarket android auto head unit, have a rough idea on how to do it and just need to buy an adapter to connect up...but dont want to buy the wrong one. I think most likely It'll be a 4pin connector, but some Toyota's have 24pin connectors etc. Unfortunately I have no OEM headunit to plug/unplug connectors until I isolate the reverse camera one.

Update - have managed to get the OEM camera working. It was fairly straightforward in the end. Can confirm camera runs on 6V and it is a 4-pin connector.

I had to connect up a little 12V-6V reducer that I bought off AliExpress for $5NZD. Hardest thing was finding this on AliExpress, so if you search, "Reverse Backup Camera 4-Pin For Toyota Connector" it should come up.

Wiring in fairly straightforward. Connect up the 4-pin to factory side and RCA to headunit RCA. Then splice red wire to 12V acc source and black wire to ground (used gray and brown wires from main 10-pin radio harness for this, but you would need to just go off whatever wire colour is specific for your vehicle, see https://pinoutguide.com/Car-Stereo-Toyota-Lexus/ ).

Lastly, in order to make the camera show on the screen when you put car in reverse you need to have a reverse signal going to the head-unit. To find this is just trial and error with a multi-meter. Took a couple minutes flicking in and out of reverse while checking voltage on wires for the unused connectors sitting behind the head unit. It ended up being a purple wire on a 5 pin connector, which needs to be connected to the headunits wire labelled "back" or "reverse".

 

 

 

Hope this is helpful for someone in the future!
