Thank you. But what is C302 on, the ECU? And then I'm assuming the C103 is the two ends of the engine harness that go into the ECU?

On the Accord:
C302 connects the dashboard wire harness A to the left engine compartment wire harness in the accord. It's gray with 8 cavities.
C103 connects the left engine compartment wire harness to the engine wire harness. It's gray with 14 cavities
On the CLS:
The engine coolant temp sensor (ECT) is grey with two cavities. On the engine wire harness, it looks like the ECT connects to the ECM via connector A (13). This is then output from connector E (14) to the gauge cluster via connector B (3).
Again, I remember reading somewhere that the signals used by the Accord cluster and CLS cluster may be different, so I am not sure connecting in the same fashion will get the gauge to work.
Good luck! Let me know if I can look up any more info for you.
