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

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 wire next to a black/red wire in an unused factory 12v amp plug and grounded the harness with one of the screws that held the amp in place. I used 3 of the 4 unused wires in the subway harness because they were already routed to the radio for those 3 connections. I tried to install everything without removing the seat. I was able to run everything and plug into the amp jack without doing this. But it would be much easier to just loosen 4 screws and disconnect a wire harness. And the hand wouldn't be so delicate either, and there wouldn't be a plaster on the finger. Do yourself a favor and just remove the seat. In the long run it will be faster. And I had to take it off to see if there were any options in the power amp harnesses. My new radio works as it should, but only after some modifications to the power supply and grounding.
