I have a friend that partially submerged a Dodge truck in water, talking engine and driver side interior. He sprayed the hell out of everything with WD-40, smelled like, well, you know, lol, but seems everything so far is fine.

As long as you get after the connections soon (before they start to corrode), the Water Displacement formula #40 (WD-40) will keep the connections from corroding and you won't have the electrical gremlins people can experience if they don't treat all the connections. It is a PITA to get to everything that was submerged, but it will save the truck.

Thanks guys. Been running the dehumidifier for a few days now to dry out the rig. Started pulling the toe kick electrical and sprayed it down with WD-40 and used an air compressor to blow everything out. Removed all the seats to give me room and remove the carpet. I strategically cut the carpet under the seat for easy removal. I was going to pull the plugs to ensure any water (if any) is blown out at first start. This rig has a push button (I’m not a fan-prefer a key but anyways) so is there any connection from that right side to the dash? Does anyone have a wiring diagram somewhere? Thanks.

Wiring from Toyota.
Will cost you a few bucks for a temporary subscription.
Drives me nuts this stuff isn't free.

Hey guys,
I come from the heavy equipment world which I know is different. The electrical systems, wiring harness, and ECM's all operate on a similar theory. Would that ECM in the passenger kick panel be waterproof, and would the electrical connection be waterproof as well?
If not, maybe that is where your Christmas tree dash is coming from (water allowing unwanted voltage to jump from terminal to terminal). I would imagine the fuse panel would have protected circuits from direct shorts. I would guess the harness is fine, but needs to have the terminals dried out. Worst case scenario, maybe that ECM in the lower kick panel would need replaced assuming you can dry out the harness okay?
I just don't see how this would create electrical gremlins for the life of the vehicle. When diagnosing electronics, the issue can only come from 3 things. The sensor, wiring, or ECM. Software issue's shouldn't apply to your situation.
I know this is all armchair diagnostics, I'm just spitballin' here and sharing my thoughts.

The seatbelt tensioners will die in short order if they get wet. The coiled spring will rust. Ask me how I know.

I second this. I can't see enough connectors failing from freshwater to cause a whole gaggle of dash lights to be on. A BCM or ECM probably got wet and failed.

Ok, so behind the glove box is an ECM that got wet. I sprayed everything down with WD and dried it all out. I hooked the battery to see what the dash lights would do now. They are stable like pre-start up but the information center says to put the shifter in park to start vehicle. The lever is in park. I had to manually depress the release (the little square on the bottom left side of the the shifter) to manually move into neutral to be towed but then moved it back once in the driveway. Does the ECM control this or is it another sensor like a crankshaft position or neutral safety switch? Or did I mess it up when I manually moved it for the tow? Is there something that I need to do to get it back to good?

There is a neutral safety switch. I think there was a discussion about this pretty recently here in the forum and the fix was to disconnect and clean the connection for that underneath the truck.

Like jp.vegas said, there is a shift selector switch on the side of the transmission (passenger side I think). It's subject to corrosion because it's not really sealed. One member here had a thread where he posted pics of the switch and the issues he had with removal. Access is a problem along with the corrosion that made the job harder. He took his switch off and cleaned it; which fixed his problem.

Thanks guys, I will crawl under the truck today to see if I can locate and clean it
Cheers

This switch is involved in some threads where people had a P0705 code. Here is one of them that shows the switch. There are a couple of others mentioned there as well.

I pulled the electrical connector and cleaned it with WD40 and let sit unplugged overnight hoping that the freezing temps don’t do more damage. Hopefully tomorrow it will work! Thanks for the thread

Another option is to use dielectric grease in connectors to keep moisture out. You can get it on line or most auto parts stores. However, the real problem here seems to be inside the housing of the switch - so sealing it from moisture might be a little more challenging. It's pretty clear Toyota doesn't address off road issues where water is concerned. Another case in point is the rear diff vent that some people mod to raise it up to help prevent water ingestion. I think one of these mods is in the stickies. If you do a lot of high water driving, you might want to look into it. It's a cheap mod and relocates the vent to inside the fuel door.
