Are the 2004 TJ Gauges Analog or PCI Bus if they are PCI Bus is there a gateway available from PCI bus to J1939. You all think I am crazy but I want to build a center console and add a spare Lowrance HDS 9 Gen 3 MFD touch screen that I have. I have another unit in my boat and think that it would be well suited for off road applications, with GPS, Maps, Media, Engine Management and fuel data, it communicates with NMEA 2000 Protocols and can be interfaced with J1939 Protocols via gateway and it can be interfaced with Can bus Protocols via a gateway and a gateway is available for analog gauge interface, however no Gateway is available for PCI bus Protocols.
