TCS 1665-HP IB-MB3 Motherboard Adapter Board - High Pins w/ KA3-P Keep-Alive

This motherboard is designed to replace the original lighting board in various locomotives. The IB-MB3 will fit a wide array of locomotives such as those from Broadway Limited, or other models factory-equipped with QSI sound decoders.

Be aware that there are a few styles of motherboards which look very similar, so visually comparing your model to this motherboard is highly recommended.

Included with this motherboard is a Plug-in Keep Alive® for smooth operation over troublesome tracks. Pair with a WOW121 for unparallelled sound and interruption-free performance!

NOTE: This product does not function without a decoder. Pick up an EU821 or WOW121 diesel decoder to use this product.

NOTE: TCS motherboards feature on-board resistors for use with LED's. This product is not intended for use with incandescent bulbs without modification or an external power supply such as the VR1.5.

The IB-MB3 has plugs for connectors to interface with the functions of your locomotive. If your model does not include these harnesses, or you would like to install your own, they may be purchased using the Wiring Kit option.

Harnesses required for this motherboard:

• 2-Pin JST Red & Black (x2 - Track Power)
• 2-Pin JST Orange & Grey (x1 - Motor)
