Need Wiring Diagram for 2020 Tundra

Ok, so I'm in need of the wiring diagram for a 2020 Tundra. I can't find it anywhere online. My problem is my Factory Stereo will not power on at all, and my adjustable mirrors don't work either. I'm thinking defiantly related but I've checked all the fuses and they are good and I can't find a fuse for the mirrors so I'm thinking they have to both be on the same relay somewhere but I have no idea which on. Does anyone have any insight or access to the wiring diagrams?

 

Are you sure you don’t have a blown fuse? There are 2 fuse boxes. One under the hood and the other under the driver’s side dash.

 

If I do have one I can't find it. I checked all the fuses in both with a test light. The only one I don't have power to both sides of is the one labeled USB. The larger square fuses with the clear covers on top I have no clue how to test but looking at them they all look good.

 

I used a test light. The only work I did was adding an amp and sub but it was working before this problem manifested.

 

Take it back to the dealer, let them worry about it!

 

Trying to avoid 2 things. One trying to avoid spending the day at a dealer over a blown relay. Two I'm trying to avoid them trying to blame me for it because I have an amp and sub installed and trying to charge me for diag and repair all over a blown relay lol.

 

Did you disconnect the battery before you installed the new amp and sub? Did they come with P and P compatibility or did you have to get in to the factory wiring?

 

Maybe the fuse that says USB powers your mirrors too ?

 

I did disconnect the battery but ended up popping the fuse for the factory amp after I had reconnected. Replaced the fuse and everything worked afterward. This problem popped up about an hour later after I had shut the truck off and restarted it again after permanently connecting the sub amp to the battery. I tried removing it but that did not fix it. The line out converter was not P and P, I had to use wiretaps to tap into the wires going into the factory amp under the passenger seat.

 

checked both fuse boxes. All fuses good. Im pretty positive the problem is a relay I just don't know which one. That's why I wanted to see a diagram. If I can figure out which relay the mirrors go thru then that will tell me which one is bad.

 

Possibly but since there is no power going into the fuse to begin with the problem lies before the fuse which tells me its a relay.

 

yea I looked at that one yesterday, some of them are the same but alot are different than mine and some of the fuses called out I don't even have.

 

@NewImprovedRon Here is what mine look like

 

I do have that one but I would imagine if it was bad it would cause all of that stuff to not work. The MIR fuse it refers to I don't have. I think that's for power fold mirrors.
#43 LH-J/B*2 150
AM1, TAIL, PANEL, ACC, CIG, LHIG, 4WD, ECU-IG No.1, BK/UP LP, SEAT-HTR, A/C IG, ECU-IG No.2, WSH, WIPER, OBD, A/C, TI&TE, FR P/SEAT RH, MIR, DR/LCK, FR P/SEAT LH, CARGO LP, PWR OUTLET, POWER No.1 fuses

 

Tough spot. Sounds like you have some troubleshooting to do. If that first fuse fried immediately when you reconnected the battery, you have an issue someplace. Did you replace with an identical fuse? Did you use a fuse with a higher rating? I’d say you need a reputable shop who installs systems all the time and can troubleshoot this for you. I think a dealer could find the problem but that’s probably going to cost a lot of money if they want to get in to it at all. Now that you’ve tapped in to those harnesses, there’s no going back to stock and taking it back to the dealer for warranty repair. Sucks tho. Good luck.

 

No that fuse popped due to my own stupid mistake. I accidentally and very quickly grounded the power wire for the stock amp.

 

Thanks and yea I'm out of ideas as well.

 

@TundraTex I hear you're the man to talk to about wiring diagrams. Any help you could provide would be much appreciated.

 

So I figured it out, and we will just say that was probably one of my most dumbass moments lol

 

Your only a dumbass if you do it twice!!

 

Good point lol I think we will stick with that logic lol.

 

The problem was in the very beginning when I was looking for the AMP fuse I pulled the ECU-ACC fuse thinking it maybe it and when my dumb ass put it back I put it back in the wrong fuse slot. So like I said, I'm a dumbass.

 

Ya but isn’t it great to have it FIXED?? Nice!

 

Yea it defiantly is!

 

Oh. ROFL! Yeah, that'd do it. I've not done it on this truck but I've done equally stupid things, so I'm just laughing "with" you.

 

Yea me too!

lol its ok I deserve to be laughed at for that one lol. I have laughed at others for it lol. This is the first time I've ever made that mistake.
