Hello Kids

How are we all?

I am wiring up a reversing camera and a reversing light. I just wanted ideas or let me know i am on the right track. Now I want both the camera and the light to function when in reverse, but also working independantly of reverse and each other. So.. I was thinking. The camera and the light can run off the same 5 pin relay with double "87" plugs to power when in reverse using the reversing light in the taillight combo to power the relay switch. I then was going to run 2 normal 4 pin relays to run them seperately via a switch on the centre consol.... right track?

Why is it before every trip, there is always something to do... I thought i did it all last time!

cheers

G'day Adam,

After wiring the "active" wire from the reversing light to the relay, there is no reason why you couldn't run a separate active feed, (preferably from a fused circuit) through a switch and then to the same point on the relay that comes from the reversing light. Vehicle DC power is all fed from the one source. (Battery)

Am I making sense?

Basically, two active circuits. One from the reversing light, the other from the switch and both terminating at the same point on the relay.
It doesn't matter if feed 1, feed 2, or both are active at the same time.
The return (negative) path can be commoned together.

Hey Sandman

If I run a active feed to the point where the reversing light on the relay is, will the cars reversing light come on when i activate the light from the switch?

Adam, please flick on the info when you get it. My DVD player has arrived that you found on Ebay for me and the camera should arrive early next week, if it doesn't get here this one. Got a 90 degree one which should be good on that 7" screen. Good buying when I see a similar DVD promoted at close to $100 more!
Cheers,

No Adam,

The Reversing light will still need its own switch closed (actuated by the reverse gear selector) to complete the circuit to the return wire.

Wish I could draw you a diagram. A picture is worth a thousand words.

Crazie

i did the exact same wiring for a reversing light on my old Hilux.
flick me a message with your email address and i'll fling you the wiring schematics of how I did it.

cheers,
Sam.

Would you really need a relay? these things only draw milliamps...

Adam has asked about the wiring of the relay because he wanted to switch the camera independent of the reversing lights. If he had it connected and the switch powered the camera, then the reversing lighs would come on at that stage.

Acutally you aren't supposed to have a picture on screen while driving forward, but how it differs from a mirror I just don't know :-) My camera should arrive any day so I have an interest too.

Oh bugger... I have mine on the back of my van so that I can see idiots that sit on the van bumper, now you're telling me I'm not allowed to do that? I have mine wired so that I just turn it on when I want it, 3 position switch, off, on, on with led illumination...Had one look at the Jackeroo wiring schematic and it was so simple to just find a 12 volt supply and run my own wires...

That sounds fair enough Mr F, but perhaps if you were to drive faster they wouldn't bother sitting there. I have a 110w reversing light if I want to use it so got mine without the LEDs

"but perhaps if you were to drive faster they wouldn't bother sitting there"

uhmm... I find that even though I'm already breaking the speed limit, just in order to "keep up" with traffic, it still happens. You could be doing 160 and some idiot will still want to beat you because you are in a 4WD and "shouldn't be in front of me".

If you want to be able to switch on the Reversing camera with a separate switch, then connect a Diode with the Band-end to the Camera and the other end to the reversing lights. Now connect a switch between +12 and the Camera.

The Diode prevents the reversing lights coming on whene you reverse the switch.

Buy a 1 Amp diode from Dick Smith or Jaycar.

I just wired my camera to the parking light circuit, via the trailer connector. If I want to use the camera, I just flick the parkers on. If I want the parkers on, but not use the camera, I just leave the monitor turned off.
Works OK and very simple.

I like that idea.
I just installed a camera today but I am sorry to say I have the camera connected permanently and turn the LCD screen on when I need it.

I found it to be very dissapointing as I mounted mine in my bumperbar and it gives a weird view which I don't like. As my screen has dual inputs I am thinking of getting a good camera and mounting it up higher and pointing it down.
