Metra 70-1761 Radio Wiring Harness Fits Select 1987-UP Toyota Vehicles Power + 4 Speaker (Packaging May Vary)

Great harness but it's to be used with the connections at the factory amp ( matte silver box to the right under the glove box). So can be used to connect to new radio harness ( you will have to run additional speaker wiring between new radio and this harness) or to install your own amp. I use a 9-volt battery to test which speaker cable goes to which speaker. Be warned, on a 2000 ES300, these adapters fit perfectly for the wiring that goes to the hazard and time clock, DO NOT USE THESE ON THOSE CONNECTIONS, use for connection under glove box.

The color codes on the wires matched exactly the ones in my aftermarket radio (some cheap knockoff Chinese radio). Everything functions real well with no issues!I used a soldering gun and heat shrink boot coverings for a cleaner look. 2005 Tacoma.

Exact fit connector for Camry. The wiring was straightforward. All the wires were pre-stripped. The colors matched exactly. The quality was good.

2004 Sienna. I was upgrading the original stereo/JBL system with Planet Audio P9640B. The original stereo had 20-pin socket (relatively big), 12-pin socket (small) and another 20-pin (small) socket. Got both 70-1761 and 70-8113 because I wasn't sure. First tried 70-8113 for the bigger 20-pin connector. It fit but no sound was coming out. Next, I tried to connect 70-1761 but these connectors were completely different from the 12-pin and 20-pin harnesses. I was really confused because about 90% reviews gave 4 or 5 stars and said they fit perfectly. about 10% or less reviews said they don't fit and completely different connectors, which was exactly what I was experiencing..... I really didn't want to be one of those clueless 10%.... After hours of googling and searching, browsing, I almost gave up, then deep down in the search results (like 4 pages back) from siennachat.com, someone mentioned this "there's a separate amplifier down low, back behind the bottom area of the central console, so below the radio and closer to the front of the van. When replacing the OEM head unit with one that provides its own amplification, one must unplug the 10-pin and 6-pin connectors going *into* the amplifier, then connect the commonly mentioned Metra 70-1761 to the 10-pin and 6-pin connectors you unplugged. From there, you should be able to follow the usual instructions that make no sense when you're staring at the 12-pin and 15-pin connectors you pulled out of the OEM head unit. It took me forever to piece all of this together." Wow... this was it! Followed this instruction and connected all the speaker wires and power wires, then, everything worked perfectly. (Here, he said 12-pin and 15-pin as opposed to 12-pin and 20-pin, maybe his was a bit different in the pin-setting, anyhow, regardless of this small difference, that's exactly how to use Metra 70-1761.Cheap and working great, but why 4 stars? Because there's no instruction whatsoever, and I had to spend almost 2 days figure this out....

Worked like a charm with our 2007 Toyota Sienna. Decent quality.
