    Well, that is a little close to repair with splicing, you might be able to get them soldered, but I wouldn't attempt it. I think at this point either a junk yard for a replacement harness, or splice to the new HU harness on and go from there.

    Keep us posted on how it goes with your neighbor.

    If you are up to learning more from this experience...

    Here is some great reading on how to service Toyota connectors, pin, de-pin and such...

    https://www.toyota-tech.eu/wire_harness_rm/RM06H0E.pdf

    I know it might seem daunting, but I have successfully repaired botched up harnesses like this one (and worse) countless times. It is not fun but sometimes you just have to.

    Otherwise, the junkyard is your next best, economical alternative to getting back to good to move forward on this project.

    Best!

    You should really purchase the reverse harness i posted in post #24. This will repair the connector that you cut off. From there, purchase the wiring harness made for installing an aftermarket radio in your truck.

    Once you have that we can tell you which wires go to what.

    you should go to a pro and have them fix it....as someone who has "paid for my learning" many times...just pay for your learning here and use Crutchfield from now on. they would have sent you every harness you needed with instructions step by step. Ive been doing car stereos in my cars for 18 years and I find them to be the best one stop shop for me. next to going to a quality shop and talking to someone about what you want. which i think you are at the latter point as there not much left to work with and something fried when you cut all those wires at once....i know from experience doing so with an AC unit...worst idea ive had. Really paid for my learning that time.

    I have to say that I agree 100% with just take it somewhere and get it looked at by someone with experience.
    I keep asking the same question I hope you noticed because if you have no power to the radio nothing else will matter until that is fixed.

    Looking at the way you removed the wiring from the factory plug it is almost impossible to think that something had the smoke let ot from that process and I bet an installer will be able to quickly understand what happened and effect a repair.

    I have been doing this since the '60's and that nest of wires that you pictured just has bad luck written all over it!

    I would not try to turn the key in the ignition either until you clean up that wiring so that nothing can short anymore too!

    Did you test the blue/yellow for 12v while the car is off and the grey for 12v while the ignition is turned to acc? Clip your test lights ground the brown wire and let us know. Dont chase down fuses until you confirm power at the device

    You must confirm power before moving on to troubleshooting.

    You posted a link to Scoche, that's not gonna help him much. Wrong link maybe.

    He doesn't have the cash to go to a pro. He does have time, time can be as good as cash if you make the most of it.

    Where are you at Ashton? Just curious.

    My bad...that was supposed to be a link to the scoche website directing him to the reverse harness #TA02RB which can be wired into his factory wires to replace his original harness that was cut off. This would essentially get him back to OE and give him another shot to correctly installing the radio.

    Not sure how to directly reply to people but I am in Florida darkness but I had figured out there isn’t a single wire in that rats nest that has power going to it

    When you cut through the whole bundle of wires, you cut through the constant 12v hot and the ground at the same time. I'm sure there is a blown fuse you need to find. Because you're so new to this I need to ask, did you ground the other end of your test light to the brown wire coming from the Tundra and did you check your new test light on the battery to confirm it works?

    Actually now would be a good time to say: "Dude, just replace the main radio fuses, then re-test!" (but only after carefully separating the wires so they don't short against each other, dammit!)

    I suspect it's a blown fuse. We clearly see a 12v wire touching a ground in his pics. He must've blown a fuse!

    Ok kid... I got crap earlier for calling everyone out for trying to get you use a multi meter/test light, then the towels started flying in telling you to take it to a shop as soon as you showed the harness.

    BUT, I’m still shocked that a 15 year old can google to find this forum, but can’t google his own question, so let me teach you a valuable lesson:

    Hint#1: let me point you in the right direction: https://caraudiotips.blogspot.com/2013/01/toyota-tundra-factory-amp-bypass.html?m=1#google_vignette

    Hint #2: you blew a fuse, actually 2 fuses. So it’s up to you to google and figure out which 2, then replace them.
    Hint#2.5: if you don’t have a correct fuse, NEVER replace it with higher amperage fuse, but you can with a smaller amperage fuse. Best action would be to use a correct amperage fuse.

    Hint#3: before you go screwing shit up again, go google on how to wire up a radio harness without blowing a fuse.

    Moving forward, go look up how to things before you go ball deep first.

    I'm in the middle of an install myself, and the previous owner hacked up the factory harness. I ordered the part you suggested. It arrived today, and it isn't correct. It looks like that's the part number for non-JBL trucks. As far as I can tell, Scosche doesn't make one for JBL systems.

    I'm looking around for what I need, and I think this Metra one is it. Below is a picture of what's in my dash right now. Half the wires are cut, but at least the connectors are still there. The Metra I linked to has the upper connector, but not the lower.

    Ashtonp25 - I'm near Melbourne. If you want the TA02RB harness, you can have it.

    It looks like they tapped on the aftermarket radio harness to the factory one by splicing and not using a wire harness that would normally plug into the JBL plug (top harness). Just bypass your JBL amp. You’ll thank me later with the sound quality improvement.

    You are correct. Hack job everywhere. I was already planning on bypassing the amp, but they already did. My original plan was to update the head unit and add a small sub. But after seeing the quality of what's been done, I'm ripping everything out and rewiring a whole new stereo.

    Ah...this just looks like a shitty job done by a stereo shop, the reason I’m saying that is because they used a 9 wire to bypass the amp and not a lot of amateur stereo enthusiasts know what it is. They didn’t use the proper bypass harness because not all stereo shops have it in stock and when customer wants something same day, you improvise.

    what you want to do is leave the harness in the 2nd picture alone where it’s connected to that wide yellowish plug. From what I can tell in your photos, they tapped on to the right wires. What you want to do is tap onto what I have circled in the photo color for color. Those are speaker wires that are ran past the factory amp and tied into factory wiring (at that wide yellow plug) so the installed didn’t have to run new wires through door boots to each speaker. That will leave you with constant power (yellow) switched power (red) and ground (black) from your new stereo to be able to tap onto how the previous person did it. Most likely you’ll have a couple of extra wires coming from the new stereo depending on features. It looks like there was a screen there since I see lime green wire which is usually the parking brake.
