Hi, thanks for writing.
I am not 100% sure, but I think that my Windsor Monaco 40 PST has a Roadmaster chassis.
It does indeed have a diagnostic port left of the steering column.
Here's something else: It has a small Sony monitor in the dash for a back-up camera. Its 'View' button lets me view engine performance information, such as coolant temperatures, turbo boost, MPG, etc.
As I was looking at Silverleaf products, I was struck by similarities of this display and what I saw overlaid over the rearview camera, on my display. It does not look like the same product, but similar functionality.
Could it, possibly, be that I can use that screen to vies engine codes? I can take a picture of it if necessary, and post on my website.
Thanks
