Review on 🔌 Pioneer Radio Wiring Harness: Toyota Compatibility for Non-JBL Models 1987-2017 & 2016-2019 BRZs by Samiran Pusarla

I thought I'd save time and buy this pre-wired harness. Bad idea. Disclaimer: It came without instructions. Second, it was connected incorrectly! I spent 7 hours fixing the installation before finally realizing that two wires were in the wrong place. (Luckily I had an old wiring harness to compare with.) I had to use a special tool to pry the wires out of the connector and swap them out. After that he worked like a champ. Purchase at your own risk.
