Silverleaf install

Looking for some help. We have a 98 Affinity and would like to install a Siliverleaf unit. My problem is locating the 6 or 9 pin connector I have looked all over under the dash and under the trans selector and switch cover on the left side of the drivers seat. I did locate a 12 pin connector in the electrical compartment on the drivers side in front of the wheel. But after talking to Silverleaf they are not familiar with that plug. I have also called Country Coach and they looking for a solution. Anyone out there run into this problem?
Thanks Carl

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
and look for the VMS200 install manual.

If you have a Cummins make sure it is an electronic version. My engine is the first electronic version. The plug can be hidden well under the dash. It probably has a cover on the connector and may be difficult to find. It is probably 6 pin. The mfgr should be able to find out for you.

Thank you guys for getting back to me on this. Pete I have a C12 Cat. Vern at Oregon Motorcoach Center gave me the info to look behind the kick panel to the left on the drivers side down low under a bundle of wires and there it was I had looked all over the underside of the dash and was ready to give up! It has a cap marked Diagnostic Connector but you are right its the 12 pin square Allison plug and has 4 wires. Silverleaf said they can work with that.
I ordered the adapter cord and the software info for the C12 425hp so hopefully I will get what I need. I've been trying to decide what notebook or tablet to use sounds like you use Microsoft Surface and that works for you so I will check into one of those.
Thanks again
