What adapters do
They map running, turn, and stop lamps between plug shapes. Electric brakes and aux charge need real seven-way wiring and a controller — an adapter alone is not enough.
Canada tip
Keep adapters clean and stowed dry. Salted road spray inside a cheap adapter is a classic intermittent-light cause each spring.
