🔌 Metra 70-8116 Amplifier Bypass Harness for 2000-2004 Toyota Vehicles with JBL Amplified System Review

When I checked the internet it said it wasn't compatible but I watched a YouTube video of the same wiring harness model and machine and decided to give it a try to try , I'm glad I made that decision because I was able to finish the job

Great harness and sound/function much better than turning on the Metra amp which had terrible sound quality and reliability. long for most cars so I had to shorten it (I removed a few feet of cord)

Instructions not included. I read that you have to connect the other end completely under the passenger seat. It's hard to know which side the passenger seat is on and I've also read in other reviews that you actually have to move your seat and run the wire under the carpet to do this. For a newbie like me, that's too much to understand.

This was the only wiring harness that worked with my 2006 Toyota Highlander Limited with JBL audio system.

PS cables are high quality copper cables.

On a 2000 Land Cruiser, for which this product is described as an amp bypass harness, you will need a second connector that connects to the factory amp. It doesn't come with that. And the worst thing is that there are 0 guides for it.

Great Bypass Harness! Lexus IS300 2004 Many extra cables. Some lines remained unused. Lots of tips/tips for installation online but always missing some technical details. There are many ways to make this setting. Check all connections before applying power to the system. Dual Dyne Pioneer Touch with built-in amplifier. There is no subwoofer. Factory amplifier expanded. Installed aftermarket 6x9 rear speakers (requires brackets) with factory rear connectors. Don't burn your car by twisting wires

2000 Land Cruiser with 6-slot coupler. The cables are more than long enough to reach the factory amplifier under the passenger seat. I had 4 to 6 feet that I trimmed off even after leaving plenty of excess behind the radio. The smaller power connector is 100% useless. Disabling the factory amplifier disables the +12V DC, +12V switch and ground of the factory radio harness. I had to find mine. I connected the red wire that came with the power seats to a constant +12V. I connected a grey/silver…
