Thank you for viewing. DC converter 24V → 12V 14-pin specific. I purchased this, but no longer need it, so I am selling it. When installing an aftermarket navigation system, there was no troublesome wiring work, and it was very easy. I used it without any problems until I removed it. It was used for six months. After purchase, please adhere to the standard 3N policy (no returns, no refunds, no exchanges).
