2020 tacoma sr5 non jbl wiring diagram

im trying to install a sub on my 2020 tacoma sr5 double cab with the non jbl HU. i have the line output converter but i cant seem to identify the speaker wires coming out of the back of the head unit. i cannot find any info online about the HU anywhere.

 

From left to right

front right
front left
rear left
rear right

positive on top
Negative on bottom

 

but there is only 4 on this harness that could be speaker lines

 

They’re all speaker wires, I promise.
Black/yellow and red/white are rears

 

then which ones would be ground and 12v?

 

Why do you need power and ground? They’re in a different connector

 

because im connecting a lineout converter ill get another picture of the entire back of the unit

 

If you’re LOC needs power and ground, you got too expensive of an LOC

in all seriousness, I’m pretty sure constant 12v and ground are in the grey plug.
12v is blue (or maybe a dark-ish blue)
And ground is whatever the thick wire is on the opposite end

 

the loc that i got was the scosche loc2sl
it was only $20
but heres the back of the hu

 

Did you ever figure this out. I also bought a LOC that was suppose to be plug n play but its not. I’d hate to have to splice into the factory wiring.

You can see the plug for my LOC I’m holding. N

 

That LOC is for pre-2020

the new radios are very different than the previous years. So until a company starts making plug-and-play LOC’s for it, you have 2 options

1) splice the factory wiring. Super easy

2) buy about $100 worth of Metra harnesses, use about $20 worth of them, toss the rest, and build a plug/play LOC yourself.

either option works great

 

So rather than return this. It seems since I’m just running a mono AMP I would have connect the Green and Grey wires going into this LOC I have and tap them into 2 speaker wires? And discard the rest of harness?

 

That is correct.

post 1 shows the connector you need. In post 2 I list the speaker wire locations

 

So the one connector shown above has all the speaker wire connectors, my question is where is the remote wire to connect to the aftermarket amplifier to hook up an external speaker and/or subwoofer amplifier?

 

The connector i bought for 2020 won't work as plug n play. I had to splice it into the factory speaker wires. Honestly if I had to do it over I'd find a better convertor. The wire was so tiny in there my quick splices weren't making good contact making me think something was wrong with the amp. Also I ended up getting the REMOTE ACC 12v directly from the Fuse box by left drivers side kick panel. I bought a FUSE wire adapter. Worked like a charm.

 

Thanks for the info! Which fuse position did you add the adapter to? I was going to use a 9 wire speedwire, which i already ran from the headunit to behind the rear seats in hopes to use the same headunit adapter you have in your first post (which after tearing apart the dash is not the one for the 2020), but was seeing if anyone knew which, if any, wire from the headunit is a remote wire that I can use to signal the amp. If not, i will rerun a wire to the driver's side fuse panel like you mentioned, which will work for sure!

 

I’m working the same problem/ project.

I need to know the location of the remote wire for my amp install. The back of the radio is a hot mess, so would love pic or location for that fuse install trick!

I got a 2018+ Camry harness (full PNP), from *********. Here is a link to the just “add a sub” harness.

you’ll also note the rear speaker factory speaker harness are for a Camry/Avalon as well. I don’t have that link sorry, but I know someone posted about it on this website.

IF you can get taco tunes to get you the right harness you can run speaker wires back to your radio so you don’t have to re-wire your doors. (Plug and play so far)

Looking forward to learning the location for the remote wire.

here are some pics of what I’ve got done so far. And yes I’ll solder the wires once I know everything works/is connected right. Also, there is a JL stealthbox as part of the final project.

 

I have the same head unit..but I dont have rear speakers in my 2020 access cab

 

Ok

 

Sorry just trying to clarify if the Camery harness work for the 2020 Tacoma?
