I doubt you have the connector you are looking for. On my 2000 Magna, the previous owner connected the JIB to the rectangular transmission connector. I had to do the same thing on my previous coach so I recognized the wiring.
Someplace on the Silverleaf site is a document with how to connect to the transmission plug. I used to have the document but recently upgraded to a new computer and I haven't found that file. Try going back to Silverleaf and tell them you need to connect to the transmission connector and they should be able to help you.
If you have a CAT C10, the included engine file is not correct. You will retrieve torque values higher than the engine can generate. I don't know if any other parameters are incorrect but I assume the horsepower will be reported incorrectly. I've sent Mark the correct data for my CAT C10, 385HP engine but he has failed to develop a corrected data file. I am really disappointed that Silverleaf has not corrected the engine file.
I run VMSpc on a Microsoft Surface Pro with Windows 8.1 operating system. My JIB is the USB box. I would like to have the bluetooth box but I'm not going to spend the money for it.
Oh, if you do request help from Silverleaf and you have a CAT C10, ask for an update to the engine file. Perhaps someone else requesting the file will motivate them to publish a corrected file.
Just found the Silverleaf file. Mark at Silverleaf replied to a forum response with this:
Re:Need wiring diagram for Allison Plug.
Our Wiring Diagram is "cleverly hidden" in our VMS200 Install Manual on page 5.
The VMS200 Install Manual
is located on the Manual Download Page
If the link is not good, try this: http://www.silverleafelectronics.com/?q=node/10
