Mobile Remote-Mount Conversion Adapter Kit for MOTOTRBO Radios
Genuine Motorola Solutions Original remote-mount conversion kit with transceiver interface, head adapter, dismantling tool, and mounting hardware.
The Motorola PMLN6404B (also cataloged as PMLN6404) is an authentic original equipment manufacturer (OEM) mobile remote-mount conversion adapter kit engineered specifically for MOTOTRBO digital mobile two-way radios. Designed for emergency response vehicles, commercial fleet transports, public utility service trucks, and heavy equipment cabs where dashboard space is constrained, this kit provides the mechanical hardware required to convert a standard one-piece mobile radio into a two-piece remote configuration. Sourced directly from our verified inventory of Motorola Two-Way Radios & Accessories, the PMLN6404B enables secure separation between the primary transceiver chassis and the operator control head.
Engineered to optimize vehicle cab ergonomics in accordance with driver safety guidelines under OSHA Standards, the Motorola PMLN6404B allows fleet technicians to mount the main RF deck out of sight under seats, behind cabs, or inside equipment trunks, keeping the control head easily accessible to the driver. The kit includes precision-molded transceiver front and control head rear adapter plates that maintain factory ingress protection against dust and water splashing certified under IEC Standards (IEC 60529 IP54). Shielded internal circuit interconnects prevent bus radiation and electrical interference compliant with FCC Standards Part 15 Class B, while heavy-duty retaining latches withstand extreme road vibration certified under DoD Standards (MIL-STD-810H). The kit includes an OEM dismantling tool to release factory chassis tabs safely without cracking the housing. Note: Interconnect separation cables are sold separately.
Key Features & Benefits

Frequently Asked Questions
What is the difference between part numbers ending in "A", "B", or having no letter?
There is no functional, mechanical, or electrical difference. Motorola Solutions uses trailing letter suffixes (such as A, B, or C) to designate internal manufacturing revisions and production lots. A kit cataloged as PMLN6404, PMLN6404A, or PMLN6404B contains identical adapter plates, hardware, and tool components, and shares identical transceiver compatibility.
Does this kit include the separation cable?
No. The PMLN6404B includes the mechanical adapter plates, dismantling tool, and mounting screws, but does not include the interconnect cable. You must purchase a separation cable separately depending on your vehicle layout, such as the PMKN4144A (5 meters) or PMKN4143A (3 meters).
What is the purpose of the included dismantling tool?
The dismantling tool is engineered specifically to release the plastic side snap latches holding the control head to the radio body. Using standard screwdrivers risks gouging the housing or breaking the plastic locking tabs, while the official tool allows non-destructive disassembly.
Can I convert the radio back to a dash-mount configuration later?
Yes. The conversion is completely reversible. By removing the PMLN6404B front and rear remote adapters, you can snap the control head directly back onto the front of the main transceiver body.
Does this kit support both numeric and full-color display control heads?
Yes. The adapter plates are engineered to fit both numeric display (e.g., XPR 5350 / XPR 5350e) and full-color alphanumeric display (e.g., XPR 5550 / XPR 5550e / XPR 5580e) MOTOTRBO mobile control heads.
