I still have some brand new "INSTRU-LINK SAE J1939 INSTRUMENT CONTROLLER/s." in stock. I'm asking $50 apiece + shipping for this units. If you ever have a need for one of these and if you do your research you will find this is a very fair price.
Keep in mind this controller is the one that converts the J1939 Bus Data to the proper signal/s so the dash instrument gauges used by Monaco can display the data coming from the Engine ECM.
Also don't get confused about the other module that looks similar. This other module is also a J1939 module, but it's a J1939 Aladdin Bridge which converts the Data Bus signals to be used by the Aladdin or Aladdin JR Main Modules.
I DO NOT have any of these J1939 Aladdin Bridges. However, used ones can be found at a few of the Salvage Yards.
In many cases both of these units are usually installed inside the dash. Mine were just tie-wrapped to the wiring bundle inside the dash. The plastic cases on these module are identical with different nomenclature. The INSTRUMENT CONTROLLER has two connector plugs while the Aladdin Bridgr has only one connector.
Both of these units are getting very difficult to find. Some suppliers, when they do have them really jacked the prices up. I've seen the prices go from $150 to $450 in just the last year.
I've been looking for the J1939 Bridge for my own coach, but I'm not going to pay $450 for one, just so I can have a monitor display my engine information. I'd use that money instead to upgrade to Silverleaf.
