Auxillary 12 Volt Power in rear finally! (Tapped into trailer hitch auxiliary power)

[drrussellhogue]

Are you hardwiring something vs using plug in truck bed?

Tapped into 12 volt trailer auxiliary which is controlled in Towing section. Ran wire to truck bed side panel where I can now charge phone, power lights and power my fridge cooler!!

Are you hardwiring a fridge instead of plugging into the truck bed outlets?

I was originally thinking about tapping into the wiring that’s on the roof…but ended up getting an external power supply. I was thinking about AC, Fridge, griddle and coffee.

I’ve always wondered what it would feel like, to be this smart! Kudos as that’s outstanding!

Wait, wait, wait! Are you in Santa Clara? If so, are you for hire?!?!

hardwire.

So what’s the wattage limit (electronic fuse I assume) on that and does the car have to be in trailer mode to use it? Does it turn off when the car turns off? Is it influenced by the “leave auxiliary power on” checkbox?

Did you have to remove the rear bumper to hardwire it at all?

 

[hemiarch]

I hate to ask. I know you’re off being an oracle genius somewhere else, but could you please explain what we’re looking at here with maybe some specs if you know them @mongo ?

400 watts or around there, 30 amp. Shows limits on truck manual. No trailer mode needed. Does not turn off. Just need to use Trailer on off. Shows in photo.

no, just need to lower the rear plastic cover underneath the receiver to reach the clips that hold the Trailer Plug to receiver. Very simple, bolts are 10mm. Can tap into Auxillary Power Supply and Ground wires on harness once disconnected.

I love it, where did you get the 3-plug power port?
great idea tapping off the 12volt already in the rear. I just purchase the 4-pin trailer plug adapter from Harbor freight, but the plug needs to be in place, your idea this eliminates this.
brings 12 volts outide the cab.
I also saw last week someone ran 120 volts to the frunk, 2 plugs and 2 USB ports, another great idea for picnics and outdoor summer concerts and car shows. etc. Frunkgating!

That 270 degree canopy is sweet, how long does it take to set up and is it one person operable

love this forum for sharing Idea's and new uses

just run from the 7 pin. that leaves the 4 pin free for trailering.

Your first electrical service issue at Tesla will be fun, promise. Regardless of how you did it.

If you used something like this you could just unplug for service.

I found the drawing wrong. Wire colors are not what Tesla provided in manual. My trailer auxiliary power wire was black and the ground white. Also, you don't need to us trailer mode on, just need to select auxiliary power in trailer menu but you also need to select "keep power on" in Putlets and Mods. Or power will turn off in 2 minutes.

uht oh hater alert. Not a single issue will come of this, ever. Promise, so you can now move on.

Can anybody think of a reason not to use such an adapter?
