Multiple SLMs with a C125 Dash

[benmtech]

I would like to use 2 Shift Light Modules with a C125. These would be used to show heading deviation left or right from a pre determined heading. The heading value would be supplied from a third party product via CAN. As the SLMs are CAN operated, I assume that I have to change the CAN IDs for one of the units. Does anyone have any experience of this or could advise on the proceedure? Thanks.
