The following pertains to devices that have a JBUS connector and a 4-pin LMU power cable (part number 5C888) attached to the LMU.

Caution: Some JBUS vehicles operate on 24VDC. In situations where ignition and/or power is hard wired to the 4-pin LMU power cable, it is imperative to have matched

voltage levels. Any mismatched voltages can create a problem. For example do not use 24VDC power from the JBUS simultaneoulsy with 12VDC from the LMU power

cable, or vice versa, as this could damage the board.
