222S Trailer doesn't activate my factory brake controller

[Farmdog267]

Looking for insight from those who own a 2020 or newer Chevy or GMC truck mostly... I have a brand new 222S and took it out for the 1st trip and I noticed that my factory trailer brake control doesn't illuminate when the boat trailer is plugged in to the truck. The truck is a 2020 Silverado 1500 Z71. We did opt in to have the dealer install brakes on the 2nd axle. The light illuminates when I tow my camper or atv trailer but I wasn't sure due to the style of brakes if it was supposed to light up or not. I have a call into my dealer and waiting to hear back.. Thanks for any insight!

**EDIT the trailer lights all work as designed.**

It has surge brakes so that’s probably why it’s not lighting up..?

Yeah, surge brakes don’t use a brake controller. They’re activated via the coupler of the trailer, and inertia. Your trailer plug probably has five wires. Ground, running lights, left turn, right turn, and the last wire is backup lights. That wire deactivates the trailer brakes while you’re backing up.

The trailer on my 2023 does not deactivate reverse when backing. Every other trailer I’ve had with surge brakes did however. You have to insert a key in the hitch to block it from sliding. I haven’t found it necessary to do that to launch tho.

Then you should get it fixed or be sure your 5th wire is connecting. These will hardly ever activate at launch, as the trailer is going downhill. If you trying backing up a driveway, or a parking lot with a slope it will activate as it takes that pressure to compress the tongue.

For safety sake, got to a trailer shop and have them check your wiring and actuator. When setup with a 5 wire connection, no key is needed, just put your tow vehicle in reverse.

Good luck,

I really don’t think my trailer locks out automatically in reverse. At delivery my sales guy told me it didn’t. I see no solenoid in the tongue. I have had 3 previous trailers that did have auto lockout and none of them had anything that looks like the attached pic. But maybe I’m wrong.

What does the electrical plug look like

Exactly, is it a five pin? Then it has lockout like every other trailer packaged from yamaha if four pin, it does not

Well I just learned 2 things. Ready EVERY word of all those safety stickers and don’t believe the salesman. Yes 5 pin (actually 7 but 2 aren’t used). Thanks!
Cheers

Perfect. I swapped my previous trailer for 7 pin as well. They are just more durable.

Combine this and led lights and you never have a reason to unplug your trailer. Except to unhitch.
