🔊 Upgrade Your 2010-2019 Toyota Tundra Factory Amp: AutoHarnessHouse.com AHH-4438 Review

Perfect match for factory amp wiring harness. Their website gives a simple explanation. The installation went great!

Everything came as expected.1. After posting the market color code, this is easy to understand. 2. Good solid cable wires

The wiring diagram is easy to understand when you have the plans in front of you. That's why I didn't give 5 stars. No documentation diagrams etc for him. That being said, my DIY made it easy to add an amp.

The harness itself worked great! But it would be very helpful if the seller/manufacturer could provide a diagram. Some wire colors don't match, so you'll most likely need a chart to match everything. Or at least mark the wires for the end user. In general I am satisfied.

Used to bypass the factory amp and run Alpine ktp-445u. You'll need a wiring diagram for your vehicle that matches the amp, but once hooked up you've created a plug and play wiring harness to run the aftermarket amp. I also used mine to hook up the rear speakers for speaker level inputs for a small subwoofer.

Worked great on a 2019 Toyota Tundra with a factory (non JBL) amp. When connected directly, the length was sufficient to connect the new JL Audio 400/4. I read other reviews that said this was not properly fixed for their Toyota. Not sure how it is, Toyota uses the same pin for all vehicles that use this connector. This product offered both a high level input for my JL amp and a speaker output. It also has a useful remote control. The connector has a 12v pin and ground but these are not used on
