Reverse signal wire near head unit?


Robzki

Recommended Posts

I'm trying to get a new head unit wired in, I have wired in the speed sensor and the handbrake feed but I'm having problems finding a suitable feed from the reverse light circuit. I know a lot of people leave these disconnected but as I'm in there I would like to find something behind the dash or ideally in the centre console.

 

I have checked everything around the gearstick(Auto) and can't find anything.

 

Does anyone know where the reverse beeper box is or failing that any other places to check?

Its ok, you can stop searching now, I found it :) The reverse beep wasn't viable as its attached to the printed circuit board on the back of the speedo/rev cluster.

 

 

For future reference for anyone searching there is a 12v+ feed for the reverse wire of head units/reverse cameras in the drivers footwell.

It is a black wire with a red stripe attached to a brown multiplug. There are several brown multiplugs there but from memory it is the one nearest the floor.

Just spotted your post here and this wire was one I was looking for a week or two back on a wiring diagram.

 

It's no big deal, but according to the Toyota diagram the reverse light circuit (called the 'back-up light' on the diagram) is actually a RED wire with a BLACK stripe.
