P light, clock, stereo staying on

Park indicator light, clock, and stereo stay on after truck is off and key removed. Tried pushing key in more when turning it off and checked fuses. After wiggling a few fuses, everything turned off. An hour later, I walked by the truck and everything was back on, including the radio. It has drained the battery twice.

 

That's one of many things covered in this thread: https://www.tundras.com/threads/so-you-wanna-buy-just-bought-a-1st-gen-tundra-eh.115928/

Specifically, read the two parts I'm higlighting in red text here as one piece of text:

Electrical stuff ... and keys​

• ...
• These trucks usually don't have a ton of other electrical issues. Hidden corrosion inside the battery/alt cables happens. Sometimes, a couple thousand miles after timing belt changes, people will have startup issues because the crank position sensor wasn't properly tucked away and gets rubbed by a belt (pic), correct routing info here. There's also a similar problem with camshaft position sensor under the cam cover, where the belt will rub through (pics). There's the rodent issues mentioned earlier. Occasionally, water leaks can send water down into the ECM behind the glovebox (pics), or into the fusebox inside the cab/dash (pics & pics & pics, it happens a LOT). Many drain/vampire issues trace back to aftermarket add-ons whether the owner knows they exist or not - alarms as mentioned earlier, brake controllers, poorly installed trailer receptacles, those are some big ones.

Chances are, that is your issue, water is making its way into your fusebox and have corroded out the contacts and you have circuits that are bridging to power. This is typically because you have a leak from a cracked windshield letting water enter the dash area, or a leak from your A-pillar, or behind the windshield trim, or from a door seal, or from your windshield itself. That water is travelling down one of the wiring harnesses along the firewall, and running straight down, into the back of the fusebox, and corroded contacts inside the fusebox itself.

Pics of what that looks like are at the 'pics' links. It's not a difficult thing to diagnose, but any time you have issues affecting multiple circuits inside the truck, especially if circuits are staying on, that's the root cause.

There is a possibility you have an aftermarket alarm also, but I wouldn't expect the gauge cluster to stay on, because aftermarket alarms typically don't hook into the cluster if installed properly. But all of the circuits you mention pass thru the fusebox, and this 'staying on' symptom would be indicative of that.

 

If your headlights are on do they stay one as well?
