Contacted AI about 05 Tundra wiring harness. . .

TaLLeN9000 · #1 (**permalink**) 08-09-2005, 08:53 PM

this is what they said:

To our knowledge, the harnesses have not changed, some vehicles have an amplified system, some do not. Then amplified sound systems are requiring a 20 pin harness with RCA inputs on them. We are in the process of finalizing and testing our design this month. If you have information that you can share please call 1-800-323-4329 and ask for Ralph Turner in Tech Support, he always likes hearing from the guys in the field regarding any information(positive or negative).

Thank you,

I don't know what all that RCA input stuff means but from what I've been reading everyone w/an 05 Tundra has been hard wiring their aftermarket stereos. Maybe someone with a little more car stereo knowledge can give this guy a call. Or maybe there is a a radio wiring harness for the 05 Tundra and I just didn't search well enough. . .

There's a standard system, JBL Analog system, and JBL Digital system. The standard system is easy... It's the same connector that yota has used since 1987... Grab a harness for $5 at a local stereo shop. If it's the JBL analog system, also easy... There's a 20-pin from the head unit to the amp, but the amp has the standard 1987 harness. Remove the amp, and use the $5 harness. For the JBM Digital system, you're SOL unless you want to hand-re-wire everything. No one makes an adaptor, that I know of.

P07r0457,

OKay. . .from what I've been reading at this forum I understand that the "$5 harness" is for the 6-pin and 10-pin connectors. I believe I have the system w/the 20-pin connector from the head unit to the amp as well. Aren't my speakers connected to my amp and therefore if I remove the amp from the equation how will I connect the speakers to the after-market head unit? Is this where the RCA inputs come into play. I suppose I use RCA interconnectors to directly hook up the speakers to the head unit which will more than likely have enough power for the speakers without using an external amp.

From all of the 05 Tundra stereo posts I've searched through-I know that it will be very helpful to a lot of members if we get a definitve answer for this install once and for all. Looks like you have an 05 Tundra and have successfully done an aftermarket radio install (without splicing any factory wires I'm assuming). If anyone knows what they're talking about. . .it would be you. . .thanx in advance

All externally-amplified systems use the 20-pin connector. However, there are two types of externally-amplified systems in our Tundras -- analog, and digital. If it's analog, you'll know by the presence of a small amplifier in the dash. If it's digital, you'll know by the absence of a small amplifier in the dash, and the subsequent presence of a larger amplifier behind your rear bench seat (behind the plastic panel).

If it's analog, then you have a 20-pin harness to the analog amp... Then a 10/6 connector from the amp to your speakers. You can get the speaker leads from that. If it's digital, then you have a 20-pin harness to the digital amp... And the speaker leads are all the way at the rear of the cab.

No, and no. RCA inputs come into play only with the analog amp. And in this case, the are NOT RCA's. On the digital amp, the signal is digital! If you want to use an aftermarket head unit, you will have to completely *remove* any JBL amp (either analog or digital). As far as connecting the speakers, you must connect the speakers to your aftermarket head unit. You will NOT use the RCA pre-outs on your head unit unless you are also using an aftermarket amp. Most head units, now, feature internal amps (such as 52Wx4) and you can connect the speakers directly using the internal amp.

I have actually done the opposite... I have kept my stock head unit, and have added an aftermarket amplifier -- without using a LOC. In the process, I have had to become well-versed in many aspects of toyota's audio system. My quest to upgrade from single-cd to an in-dash cd-changer further complicated the issue.

well from your car audio newbie friendly post-I now know that I have the digital system with the speaker leads all the way at the back of the cab. Once I've selected a head unit I will work on figuring out the best and cleanest way to have wires from the back of the cab connecting the speakers to the aftermarket HU in the front of the cab. Thanx again

Honestly, the most hassle-free (and best) way is to run new speaker wire from the aftermarket head unit to your speakers.

I have an '05 and, according to everything I have read from the dealer, I do not have a JBL system. It was the system with the CD/Tape/AMFM. No changer or steering wheel controls. The Amp was located under the rear seat, in the 60 compartment, passenger side.

I had purchased the wiring harness for a Toyota, and it did not work. I had to have it professionally installed, which hurt the Ego very badly.

It took me forever to find the stupid amp. Everything I could find on TS said in the dash or behind the rear seat. It was under.

To my knowledge, it is NOT JBL, according to the dealership and/or documentation that came with my truck.

Hope this helps ~ David

Jonesie,

What did you get installed professionally-I'm kind of curious to find out what setup 05 Tundra owners are using (i.e. aftermarket HU, speakers, amps, subs). I also have the system with the CD/tape radio and no steering wheel controls-it doesn't say JBL anywhere, but I guess it really doesn't matter as long as i know that i have the system with the 20-pin connector wired to the amp in the rear.

btw,

I purchased the "status monitor" for the older alarm system per your write-up. I haven't received it yet but thanx for saving me a couple hundred bucks

Does anyone know if the VSE Subwoofer for the Tundra DC will work in non-jbl systems? I guess mainly what is involved in wiring that in? Will an additional amp be required to power the sub?

the VSE sub *requires* the JBL system. It pulls it's power and signal from the amp behind the rear bench.

If you don't have the JBL system, then the VSE is a waste of money... You can build a better setup for less money, yourself. The VSE is only good for those that want a "plug-and-play" solution.

Hey Man,
I had a Pioneer DEH-7600MP installed by a local car audio shop. I had pulled it out of my old Honda. I'm a DIY kinda-guy, so having to take it somewhere killed me.

Once they did the basic install and "amp bypass" as they called it, I took it home, added the iPod and XM hardwires, and swapped out the door speakers for Pioneer 6.5"s. I put 3-ways up front and 2-ways in the rear. I left the stock tweeters in.

I'm no car audio buff, I just wanted to upgrade the system cause the OEM wasn't loud enough. Now if I could just find a way to add a thump to it without loosing all of my in-cab storage for a decent price...

And you're welcome for the article. I was very excited to get it done myself. Feel free to shoot me a PM if you need any help or have any questions.

~ Dave

Jonesie,

I finally selected a HU and have moved on to speakers. I'll probably go the coax route for ease if installation and budget reasons. I have just a couple more questions about your set-up. After you had the car audio shop install your HU-did you feel the need to run all new speaker wire when you installed your pioneers? Or did you just get some speaker wire harnesses and go the "plug-n-play" route?
