2011 Tundra Has Radio Acc, But No Constant at Harness

I connected a camera system to the radio's acc and constant lines, and it worked for a while.   I assume the load was too high, or I shorted something as I put everything back together.   But now the radio is dead, but I have acc power - just not constant.

I've checked all fuses under the steering column and by the battery under the hood. Nothing blown. Are there fuses elsewhere between the constant 12V (greenish/blue) and the battery?

There is a blown fuse somewhere.

I think that's a pretty safe assumption. I've also noticed that it's throwing some codes with the VSC light blinking. This happened before when I blew a fuse towing a friend's trailer. But that was a quick fix. I have now gone over every single fuse manually in both fuse box and they're all okay. I am absolutely stumped. I'll give this a little bit more time before I spend the Box on the techstream website.

Well, I've got egg on my face. I don't know how. I checked, rechecked, and then triple-checked all of them, including that stubby row with 21 in it. They all toned out.   I just went to check for voltage across the pins to see if there is any parasitic load with the engine off, and I got a full 12v.   That, of course, means the fuse it blown. Sure enough it was.   I disconnected the load of the camera system and replaced the fuse. Stereo came back up.   I feel like a complete 1D10T...

Thank you for nudging me to do it one more time - this time, with my eyes open, ears listening, and brain paying attention.

I am curious, BTW, how did you know to look at 21? All of the diagrams I've found online show 19 through 22 as blanked out.   There's a fuse shown in the block, but the legend shows dashes...

Found a post in a forum that had that picture and a list of the fuses and what components they were associated with. It said Radio 1.

You need to check the wiring to the camera. It is the problem. The camera pulls no current at all. It did not blow the fuse.

no, the camera is actually four cameras and a processor that provide surround bird's eye view. And you're right even that shouldn't pull more than a half an amp. I'm pretty sure in the haste to get everything buttoned up before dark I didn't tie back the wires under the passenger seat. The last thing I did before the radio went dark was slid the seat backward. I'm pretty sure that probably cut/pinched or ground out the cable. I'll get it squared away tomorrow with some more daylight. Thanks again for your help.
