If you intend to pull a trailer that is configured with pin 6 as the trailer brakes, a wiring change could be needed. Ensure that you check the trailer brake operation as part of the pre-trip inspection to ensure that the trailer brakes are operating properly. Altec does not require the truck-mounted trailer plug to be rewired, but rewiring might be necessary depending on the trailer the customer intends to pull.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10191601-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10191601-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10191601","components":[{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ALTEC","model":"AERIAL DEVICE","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
