can

Hello all, I bought an instrument cluster from a salvage lot on eBay and am attempting to turn it on and control it with an Arduino and CAN bus shield. Unfortunately I don't have access to an S550 to datalog and pull information from so I am in the dark stuck with brute force and internet...

Has anyone located an unused or easily accessible CAN + and CAN - connector in the drivers side cockpit? I'm trying to hardwire a racecapture and pull CAN data without using the OBD port. Any help would be greatly appreciated.
