Reverse signal behind centre console

Devcore · 20th May 2019, 07:16

Hello Everyone,

I would like to connect my reverse camera to my headunit, but i cannot find the reverse signal

. Can anyone post me a picture where i can get it? Do i need to run a seperate cable from the switch?

I know it's asked several times but the pictures deleted in thoes thread

.

Thank you,
D.

I don't know if this will help you.

According to this (last pic in post 3) the reverse light wire at the rear light clusters is Green with a Brown stripe. The circuit diagram 12.29 in the Haynes manual shows it going to one side of the reverse switch. The other side of the switch has a White/Yellow wire going to reversing light relay R4/pin 30 in the passenger fusebox - this is for manual gearbox cars. For auto gearbox cars, the Green/Brown reverse wire goes from the rear light clusters straight to relay R4/pin 87.

Also (another option) - Haynes circuit diagram 12.32 says the wire feeding pin b11 on the dashboard instrument cluster is a Green/Brown reversing light wire.

Thank You Blink. I was sure they connect the reverse light signal into the cluster, because the speaker is in there. I just hope it's going thru the centre console so i don't have to disassembly my car again. But well...It's never the easy way

. Now I regret i choose the wireless method

You're welcome Gabor.

I've had the instrument cluster out of my car (not easy!) and I think the wiring harness does go towards the centre console. It will be tricky to separate the wire though.

There are two big connectors going into the instrument cluster - one white and one black. The black one does have a Green/Brown wire - see arrow in 1st pic below.

I would look behind the radio/head unit first. The harness from the instrument pack might run across from the driver's side to the passenger side at that height.
