purple/white wire on idata harness

Post by yycwrangler » Thu May 23, 2019 5:27 pm

I have connected the purple and white wire to the idata harness. This is the reverse camera signal. When I put my vehicle in reverse, it shows that purple/white wire to be hot. This wire is meant to tell my head unit that the vehicle is in reverse and to do this I'm meant to connect this wire to a reverse light in the vehicle According to back up camera install). But if I'm getting power to this wire, when putting it in reverse, that tells me that the stereo knows that I'm in reverse (no power to that wire when in drive or park). So is it part of the idata RR/harness that is telling the stereo that I'm in reverse.

When you're in reverse, does that purple/white have voltage on it or not? I'm having a hard time following. If it does and the screen isn't switching, it's a simple fix: The reverse camera interrupt in the radio needs to be set to ON.

Hi Dara

When I attach a trouble light to the purple/white ( from stereo) wire and put it in reverse, the trouble light turns on..In other words it's hot.

We provide a reverse trigger to the radio from the RR, on our purple/white wire. This cannot be connected to any other devices though, IE it can only go to the radio for triggering the reverse screen, not for powering a backup camera. The camera itself should be powered separately. Hope that clears things up for you.

last question guys.

Can I connect my camera red wire to the red wire on the harness and the camera black to the black on the harness.

So in a nutshell -

- no need to touch the violet/white wire as it currently changes my screen to the backup screen when I put it in reverse (jeep is an automatic)

- connect camera red wire to the red wire on the idata harness and the camera black to the black on the idata harness.

- RCA goes into brown plug on stereo harness.[/list][/list]

Have I got this right

cheers

that is correct, just be careful some cameras have been known to backfeed into the acc circuit (red wire) causing the radio to stay on. in this case you will need an appropriate sized diode or relay to isolate the the camera.

Sounds good so just to be safe I should find a 12 volt wire out of the harness such as the cigarette lighter

Justin

Just so as I'm clear on your last post regarding back feed back into the stereo and draining my battery..Would my screen show as being on if this happens.

In other words if the screen goes off when I turn the power off, I should be good to go or do I need to take a trouble light and check for power flow.

if this is the case, with the trouble light, which wire on the harness would I be checking

Thanks again for all your help

if this is the case, with the trouble light, which wire on the harness would I be checking I dont know what a trouble light is but you don't need to test anything, you would need to add a relay or diode to the acc wire from your camera to avoid the backfeed like i mentioned in my previous post. in this scenario you would have to contact the camera manufacturer for assistance as it would be an issue on their end not the Maestro

Thanks again for all your help
