06 tundra ltd

This harness definitely makes things easier. I did not put 5 stars due to the connector that connects to the amp harness for my tundra did not fit. I had to grind down one side of the inside corners to make it fit.

Just what I needed to bypass the OEM amp on my truck. However, I'm wishing I would have bought an aftermarket amp and speed wire instead to fully upgrade my stereo

As advertised, works fine. This item allows user to bypass the factory-installed amp but is necessary for using the vehicle's installed speaker wiring.

bypass harness worked great, I really appreciated the zip ties already on the wires that helped substantially with ease of installation. Wires reached from the back of my 4runner through to the dash with extra length to spare.

It was perfect for bypassing the Amp, although it was about 3 ft. too long it can be cut to fit. The white head was a bit of a tight fit, a bit difficult to insert but better tight than loose. The instructions where a big help in a DYI situation. Its been in my 2004 Tundra for 3 mo. and no issues.

Worked like a champ, and wiring instructions clear. I meant to have Crutchfield do it (worth the money) but doing with the instructions wasn't too bad.

No complaints

MUCH. better sound quality out of the aftermarket unit than the stock amplifier could deliver. Happy that this harness provides the "odd" speakers as well (center channel, rear tweeters, etc) which I routed under a seat in case I want to someday use them.

By-Pass the Factory JBL Amp & Use Your Head Unit's Amp

Worked perfectly for my 06 Tundra Doublecab to bypass the OE JBL amp and drive all of the speakers from my Pioneer AVH-X3600BHS head unit. The instructions provided by Crutchfield were a 1000% better than the limited instructions included with the Metra paperwork. I ran the wiring from the JBL connector (located behind rear seat on driver's side) up to the head unit in the dash using the channel in the driver's side running boards and then behind the left kick panel. This is the same path used by the factory wiring harness and it is easily accessible from inside the truck. It's a very tight fit, but there is room if you only use the wires you need (this harness is used for a variety of Toyota applications, so there are several extra wires that you won't be using) and I would strongly recommend using a small diameter (3/8") plastic cable wrap to keep the bundle together and protect the wire insulation.

Used in a Toyota Sienna

Great adapter to wire directly to your speakers! Only things lacking, and these could be big, is the dimmer control from the vehicle to the dimmer wire of the deck and "always hot" and "ground" power wires from the JBL harness. I moved some unused wires around to utilize this function. If you use this for an older Toyota Sienna, you can take out the old JBL amp and run the replacement amp from the power wire of the JBL system. But only if the new amp doesn't draw more than 30 amps. LOTS of wire to use (super long).

Good Harness

I installed this harness on a 2006 Toyota Tundra Double Cab and it works as advertised. There were a lot of extra wires for different applications, but those were easy enough to coil up and put out of the way. I would recommend this for anyone that has a stock JBL amp in their Toyota...the system sounds much better now.

Meh..

I thought I bought a harness and head unit prepped for factory plug in. That was not the case, a wiring harness that did not fit anything factory. My unit turns on and off so power is right. Still no sound. Currently it is a large clock using dash space.

Once we saw this review, our Tech Support team reached out to Chad to help him further. We'll either help him get the receiver connected and working properly, or help him return it for an exchange or refund. Lifetime tech support comes with every Crutchfield purchase.

Worked great! Much longer then needed but that's no problem. 2005 Sequoia with JBL - if you have front tweeters you'll need connect those wires with the appropriate front speaker wires. I had to call Crutchfield to figure this out.

Metra 70-8117 Amp Bypass Harness

The JBL amp in my 4runner had been acting up - losing the right side and occasionally shutting down altogether. It was suggested I use this bypass to remove the amp and power the speakers directly from the HU. Installation was a bit of a chore but straightforward. Had a few problems with the steering wheel controls but after fixing a connection had failed, SWC was restored. The bypass works fine, though the subwoofer no longer works as it was powered from the amp.

Worked fine overall. Connector quality was a little cheap. The radio power connector did not lock together. The amp bypass harness was great, though. Saved me a ton of time, instead of running new wire.

Works but lacks instructions

The product works as advertised and provides more than enough wiring for my 06 Tundra Double Cab but the instructions are severely lacking. I had to youtube the fix for why my front speakers weren't working. Simple fix, but was annoying after spending the time to rewire everything.

Factory Toyota Amp = EVIL

*2004 Toyota Sienna w/JBL.* So glad to finally solve the mysterious sound issues in my Gen 2 Toyota Sienna. The factory amp needed to be by-passed. I thought amps just amplified an input, but not this evil amp. It controlled the sound, monitoring it and decided where to allocate it. I got swirling sound (fader and balance) with variable "ghost" like EQ. With a new Sony head unit and some new speakers it was not allowing my system to function properly and HAD to go. This harness comes with yards of wire. I only needed enough to get from the head unit to the factory amp behind the glove box. The harness itself fit a little snugly, things are tight there under the amp in the glovebox anyway. I've noticed 2 Crutchfield harnesses lately that didn't seem to have an exact fit for me, but were close enough and ended up working OK. Wonderful improvement in sound and now I can tell my head unit actually has some clean power to it! I wish someone would've told me to bypass the stupid factory amp right from the start. I'm controlling the EQ and sound location now and able to use the remote app too! If you've got a Toyota factory amp, BY-PASS it!

Be ready for some work

I fully understand the desire to bypass the factory amp and use the one with a new head unit, but the work involved in my particular application simply was not worth it. My '05 Tundra amp is on the back wall of the truck cab which means running all those wires back up to the front of the truck and into the dash to connect to the new head unit. The harness comes with plenty of wire, so if you are ready to find a way to run an entire bundle back to the front of the vehicle, it probably works well. I returned mine for a different harness that allows me to use the factory amp and all worked out well. Many thanks to the folks at Crutchfield for helping me sort through all the issues and find a solution that worked!

Not worth the hastle

This is a fat stack of wires that looks like a string of lights from Clark W. Griswold. In the end i only ended up using this for the rear door speakers as I had to rewire the front speakers to avoid that BS wiring job Toyota gave the JBL system.
