Carb to Holley Terminator EFI Conversion How To w/lots of pics

That display is the optional upgraded 3.5" one for this system. I got it from a member on here who I traded the fuel pressure regulator for. In the harness there is a CAN1 and CAN 2 plug. I run the smaller display on CAN1 and the 3.5" display in CAN2. Here is the link if you want to purchase.

Do you know the specific name of the display, and was it included, or optional? I thought what came with it was the smaller handheld "controller."
