Radio headlight wire?

[BigWheel88]

So I am installing a cheapish Double Din Radio with Android Auto by brand Atoto. I have it all hooked up according to wiring diagrams afaik. The one thing that seems to be causing issues is the illumination wire. They are both orange on the metra harness and the radios harness. It seemed to work when turning on head lights things like Android Auto maps get dark initially, but it just starts flashing back and forth from day to night mode. Odd things like the right blinker not going off but left blinker works fine. I turned off illumination in radio settings which also stops it from changing to night mode when headlights came on which is not great because day mode is blindingly bright at night. turning the dash dimmer too the highest seems to help a bit but it still does odd thing with blinker. All this goes away if I disconnect illumination wire in harness but still can't have day mode at night ( too annoying to switch manually deep in settings).

I am still looking at grounds as a a possible issue. the previous owner (i got the jeep back in 2016 ) had things like some crappy rock lights, some old CB radio wiring and other things I never use installed, which I need to remove all the wiring for.

I left a meh review on unit on Amazon and I got another brand unit ( BOSS) and it did the same things so had to turn off illumination in the device settings again. The company ATOTO contacted me to try to work out issues.

They said the orange wire from head unit harness should be connect to headlight switch wire not the orange illumination/dimmer wire in metra harness. The buttons and such on unit do not dim with dash lights so it makes some sense but afaik there is no headlight wire on the metra wiring harness. Has anyone heard of this or know where I can tap into a headlight wire under dash?

Thanks. I hope all that made some sense.

A headlight wire would likely be found at your headlight switch. Depending on the year, that may be a pull switch or the MFS on a stalk. One way to quickly and easily test this would be to simply connect the orange wire on the stereo to +12v and see if it goes into night mode. If it does, and you'd rather avoid tapping into the OEM headlight wiring, then you can simply wire it to a switch with a 12V feed and engage night mode whenever you like.

It is a 2003. Headlight switch is on the turn signal stalk. I don't mind tapping into OEM headlight wiring just don't know where it is or how to find in the stalk or else where. I do prefer it to be via the headlight switch but just tapping into some other 12v feed like like lighter and putting a simple switch is probably simpler for me.

thanks

Even if you do want to get into a headlight wire, tapping into 12v would let you test just to make sure it resolves the problem you're seeing.

The Factory Service Manual in the resources section of the forum should tell you what color the wire is coming out of the steering column area.
