Was that from today? I wonder when this website update will be. I noticed that the maker background is just gray now... I'm ready for some updated pricing and more details under the accessories when you click on them. Everything is still lacking much information... We'll know when we get closer to production

Yeah I just got that today

I don't see a 7 pin connection ever coming as the tow capacity is only approx 2000

It's coming in a kit/build like this:

https://www.etrailer.com/Accessories-and-Parts/etrailer/etbc7.html

and my Tekonsha P3 controller conveniently mounts to the T slot under the HVAC controls.

In a vehicle with "only" 2000 lbs tow capacity, I think that it makes even more sense to run electric brakes on the trailer. In compact trucks, it's not like towing a jet ski or utility trailer with a full size truck where you barely notice it back there, it's going to push you around a little and extend stopping distances. It just makes sense that you'd want to get some of that back with electric brakes.

The only hard part is getting an analog proportional signal from the brake pedal to the controller, that's a stock harness signal on my Sequoia, but other vehicles and brake controllers without analog outputs often have to make do with a wire to an on/off brake light and an accelerometer.

Will the Slate brake lights turn on when in one-pedal regen?

I would argue the opposite actually. The truck already weighs quite a bit so you arent going to feel it as much as you would on a similar sized ICE. and with electric brakes youre losing out on that valuable regen. I could see stabilizing bars being valuable but probably not trailer brakes.

also, im not aware of any trailers below 2k that have electric trailer brakes installed.

Thanks for your insight. That option is not from Slate which is what I was referring to. Also the regen braking on the Slate will nullify the need for Electric brakes for small trailers IMO. MyHybrid Maverick handles breaking with small trailers and no electric brakes excellent

If you're using your slate to launch watercraft in saltwater, I would strongly recommend against electric brakes, or any brakes for that matter. Surge brakes would be a much better choice imo . You would have to use a 5 pin plug, and wire your brake lock out into your back up lights , but it would be a better choice, once again my opinion. Trailer brakes on a salt water trailer need to be used very often or they become problematic. If you can get away without brakes , you're better off.

Electric brakes can help you recover from sway or slowing down safely in certain situations.

Fortunately, the nearest saltwater is more than 4 Slate charge stops away, and that's while not towing! Lake Michigan - Unsalted & Shark Free!

I have pulled a friend's boat with hydraulic surge brakes, that didn't have a brake lock-out just a shot pin you could drop in when reversing. Salt just kills all things metal. I envy your weather in the winter, but I do not envy your salty corrosion nor summer humidity. Also, mad respect for daring to drive a compact truck on Florida roads - drivers down there are crazy!

(drivers down there are crazy!) Hey, I represent that remark.

I currently tow my boat with an under 3000# Kia and I barely even notice it's back there. Granted, my trailer is only 600# (with boat and gear)...

I've towed a lot of trailers in my life and I can't think of any that were *both* under 2k loaded and equipped with brakes.

Same here

I have an Aluma 6316 with brakes on both axels. Aluma says it 825#, mine on a certified scale is 809#. Use all the time to haul large stuff that will not fit in the suv's
