Does FORTIN have any products that would tie into these OEM wires and supply a 12 volt output to trip my relays when the fob or OEM door locks are pressed? &nbsp;Please let me know. &nbsp;Thank you for you time.<br /> <br /> Kevin GMC /en/qa/69635/aftermarket-door-lock-outputs Fri, 04 Mar 2016 17:19:36 +0000
