Metra 70-1761 Radio Wiring Harness For Toyota 87-Up Power 4 Speaker

Metra 70-1761 Radio Wiring Harness For Toyota 87-Up Power 4 Speaker

Perfect fit for my 1998 4Runner SR5, mine had no CD player and did have the factory amplifier which was removed completely.

A note for anyone with the same setup; this harness plugs into the connections that went into the factory amplifier, NOT the ones that went into the factory head unit. So if you're confused because they don't seem to match up, look for the factory amplifier and remove that as well.

I am in no way electrically inclined but this harness made the connection process ridiculously easy! Each wire on the harness is labeled with its name on a tag (Left Front +, Dimmer, Right Rear -) AND is stamped on each wire should the tags fall off. Admittedly, you may need a magnifier to read the .0005" print.

A few strips to the end of wires, a butt clamp on both ends and a crimp to lock in wires on both side of connector. Oh, the wires are also colored to match with the receiving wire and match near identically ... really nice for the lazy folk that skipped over the mention of the magnifier!

When you're done, you'll feel like you earned a certificate or something AND you prolly saved yourself a hefty install fee! Yay you!!!

It does its job. The wire color guide on the packaging needs an update though. The guide calls out two separate wires for POWER ANTENNA ("BLUE") and AMP TURN ON ("BLUE/WHITE"). But on this harness the pins for POWER ANTENNA and AMP TURN ON are connected by a short, blue jumper wire; and so there is just one blue wire coming off of one of the pins to serve both functions, as it should be; therefore there is no separate BLUE/WHITE wire that is referenced on their guide. They just haven't updated their wire color guide that's printed on the package to reflect this.

My stock stereo in my Toyota Sienna 2005 went out a few days before a family trip 400 miles away. Luckily Amazon had all the things that I needed to replace the stereo. After doing some research online, I discovered that I needed to order 3 things.
1. Stereo CD with Bluetooth (much better than my previous stock stereo at 1/3 the cost of the dealer)
2. Dash Kit for a double DIN stereo to mount the stereo with plastic moulding to fit the space
3. Radio Wiring Harness

I ordered the above items and requested 1 day shipping. We called someone to install it, but if I had more time I probably would have done it myself. I watched a Youtube video that showed me how to take off the side panels and find the screws to remove the old stereo. To connect the wiring harness, the installer used crimp caps which he did in 5 minutes. The hardest part of the installation was wiring the bluetooth microphone on the left side of the driver by removing the panels under the steering wheel and up along the trim of the window. (There is a Youtube video for this too.)

Note there is another connection on the stereo, the "Wheel Kit" so you can control the stereo volume, tuning, and selector while driving, but I opted not to buy this additional kit.

If you are like me and have the "premium" audio system in your 98 camry (xle trim) then you may notice at first glance, this harness will NOT work. That is because the factory connections this harness does work with are plugged into a factory audio amp. You have to disconnect the amp (two more plastic clips) then this harness works like a charm. I used it to connect up an Android head unit and will be doing to speakers soon as well.

TL DR: Some Camrys (XLE trim - I.E. if you have a CD player and a tape player) have a factory amplifier and you need to disconnect it to find the connections this harness plugs into, don't freak out like it did haha.

Description

Wiring Harness for Select 1987-2005 Toyota and Scion Vehicles



I bought both the 71- 1761 and the 70–1761 As I was installing an amplifier onto an existing car radio.
This made the job significantly easier. I was able to solder and shrink wrap all the connectors working on my kitchen table and when it came time to install the amplifier in the car all we had to do was plug into the back of the radio and the wiring harness and the job is done. 2016 Subaru Impreza added in an alpine amplifier.

I have a 1995 Toyota Avalon XL with a simple AM/FM/tape head unit; no CDs. I ordered a new head unit, and this harness because Amazon said it would fit and I didn't want to cut any wires. However, after actually taking apart my dash, I found that the connector was completely different.

After doing some research, I found conflicting information. As I understand it though, all 1995 Avalon models come with an amplifier, and don't have the two connectors that this harness uses. You either have to do some modification (something I have no desire to do; I'm only trying to get Bluetooth in my car), or buy a different harness that will work with the car's built-in amplifier.

I chose the latter option, and so I'm ordering a Metra 70-8112 Radio Wiring Harness which will hopefully work better. Whatever your car is though, I definitely suggest that you avoid making the same mistake as I did. Figure out what connector you have before ordering your harness.

The harness itself looks pretty nice, and I'm sure it'd work well with other vehicles. Since it looks like it'd get the job done, I'm still going to rate this five stars.

Worked great for our non-JBL 2009 RAV4 aftermarket install on an AVH-W4400NEX head unit install.

It's just a wiring harness so that you don't have to make any splices to the factory harness. You DO still have to splice the aftermarket head unit's harness to it, so keep that in mind. Whether you solder, butt splice or twist/splice/tape it, you do still have to connect to the aftermarket harness. After that, it's plug and play to the factory harness.

PLEASE KEEP IN MIND - This harness is ONLY for the basic functions of a car stereo, namely the 4 speakers, ignition, 12V accessory, ground and remote. If you also need functions such as steering wheel controls, bluetooth, ETC...that will be a different module/harness. Don't blame it on the harness if you didn't do your homework!

The adapter cables work as expected. I don't like cutting or tapping into the factory wiring so this is a good alternative when used in conjunction with the new deck harness. Use the pink/red 18-22 gauge butt connectors to tie them together and everything is taken care of. There is an extra connector (see picture) in my 2008 Tacoma for the steering wheel controls that this adapter kit does not cover. I don't have the controls so no matter. If you DO have the steering wheel controls, you will need an addl harness.

The following is for those who have never switched out a stereo before :-)

This also assumes you are either switching out a previous aftermarket stereo or the factory Toyota one, so the Toyota harness has already been assembled into the vehicle correctly.

You'll need at least some 22-18 splicers http://amzn.com/B0002ZPG8E and a decent crimping tool to finish the Metra-harness-to-stereo-harness connection, but the wires are well labeled and colored. Check the stereo to be sure it has good instructions on the wiring before attempting to install if you've never done it before. It is very handy the Metra wires come pre-stripped. if you've never crimped, just be sure to get a set with basic instructions. Depending on the aftermarket stereo manufacturer harness, you're likely to have to strip the ends of its wires by hand, so a multi-crimp-cut-strip tool is advised. Not sure if these come with good instructions, but the similar pair i picked up elsewhere did http://amzn.com/B000JNLUN4. After patching the Metra converter to the stereo harness, I just followed the stereo's instructions for connecting the antenna and the harnesses. no problem at all.

If you've gotten to this point, be sure you've already figured out how to disassemble the dash, reassemble it, and, if necessary, purchased a DIN converter. I've got a 2003 Corolla CE that came with a double-DIN factory stereo, so I needed a DIN converter that turned the extra bay into a pocket.

If you plan on using an external amplifier you can wire it in with this harness with little extra work, but still may need a DIN converter. Also, always be sure your output from the aftermarket stereo / amplifier doesn't exceed your speakers' wattage.
