09 HL install help for Pioneer AVIC x920bt

Hi Toyota Nation,



This is my first post. I have an 09 HL Base V6 (2wd) and thanks to all the posts here I was able to install most of the Pioneer AVIC x920bt connections. I also installed a sanpos back up camera that replaces one of the license plate lights. For the camera's power source I tapped into the backup light wires from the rear hatch. The only thing I'm stuck on is the location of the reverse trigger wire so that HU automatically switches to rear camera.



I've read in a few forums that it was the red/white wire in the gray harness on the driver's side kick panel. I opened mine up and there are no red/white wires. In my gray harness I found 2 red wires each with silver dots. These are constant 12v+ so the reverse mode always stays on even after I shift out of reverse.



This thread mentions there was a gray harness in the right-side cavity behind the original HU of the which the thin purple wire is the reverse trigger wire. On my car it is a blue harness and the purple wire is not active.



I really don't want to pull this wire all the way to the rear to tap into the rear backup light wires. I'd really appreciate some help on this.



Thanks in advance

Let me move your thread over to the Audio, Video, and Security forum and see if the members there can help you out. I'll keep a redirect to the thread's new location in the 2nd Gen Highlander forum.

Thanks TrailDust.



I talked to a Toyota Parts technician and he mentioned that in the HL Base models there is no harness pre-wired for the reverse light switch in the front of the car. This doesn't seem right since the switch to the reverse light should originate from the transmission shifter.



It's looking like I might have to tap and run a wire from the reverse lights to the HU for the HL Base models.
