4th Gen 4Runner Back Up Camera Adapter Harness?

Yay!! @daveeasa is here!

 

I'm going to start by taking the head unit back out and just make sure i seated Pin 2 (reverse signal) correctly into the 28 pin connector. The backup camera worked fine with the OEM head unit so maybe i just messed up something installing one of a bajillion wiring harnesses getting all this to work.

 

Well, I'm the idiot. I took it all apart and reexamined the connection on Pin 2 in the 28 pin connector and low and behold i did not seat the reverse signal pin correctly inside the connector. Fiddled with the pin (can't remember if i just didn't push it in far enough or if i flipped it 180 degrees to get it right) then tested it and wham bam got a backup camera now! Apparently i don't need a step down converter which is a breath of fresh air after all this.

Shout out to Brian at Autoharnesshouse.com, dude stuck with me through 15 emails back and forth throughout this whole process. His harness worked flawlessly once i got it installed right. I gave him his due credit/props.

So for anyone whos curious, you CAN do the T10015 Scion head unit upgrade in a 4th gen 4runner with the JBL synthesis system and retain steering wheel controls, gain bluetooth for phone music, add mic for phone calls through the car stereo, keep OEM backup camera, and keep the great JBL sound (once you adjust the

TYTO-01 potentiometer screw). Incase it was lost in the threads, the only thing i upgraded for sound was the 8" sub... went with a Rockford Fosgate drop in replacement. The only thing i lost was navigation through the head unit (even though my T10015 came with the nav module... did not even attempt to figure out how to hook it up) but that's no biggie as i 100% always use my phone for navigation anyways.

 

Glad autoharnesshouse hooked you up.

 

Ya they custom made a harness I did not see ANYWHERE else on the internet, plus customer service was a cut above.
