Pioneer Radio Install Help

[BigMike18]

So I’m installing this pioneer and I found from other users on here these items to be able to use my jbl still and steering wheel controls etc and I was recommended these items

Amazon.com: Metra TYTO-01 JBL Amplifier Interface Harness: Car Electronics

Amazon.com: Scosche TA02B Wire Harness to Connect An Aftermarket Stereo Receiver for Select 1984-Up Toyota Vehicles: Car Electronics

And I’m a bit lost on where to go from here and I’m a novice with wiring but prepared to do so

Just don’t know what to do with these other connectors from the original radio

One of the connectors, I believe the smaller square one is for the original tape deck (assuming you are coming from the stock radio). I just installed an alpine head unit and I didn’t use that connector. For the rest of your problem I can’t help as I bought the wiring harness pre configured from Crutchfield, but I also didn’t have the JBL and steering wheel controls. Sorry I can’t be of more help.

jbl equipped 4runner. stock radio needs to be turned all the way up before removal.
use the jbl amp interface.
pioneer radio wires need to match all the wires.
im surprise it did not take the pioneer rca preouts.
might need to get another wire harness to take use of the pre-outs from the radio.
