996 C2 OEM Decklid Harness Part Number Request

Recommended Posts


Could somebody please tell me the part number for the OEM Decklid Wiring Harness on a 2003 C2? When I bought my car, it had an Aero kit MK II rear spoiler and no wiring harness. I bought one for the OEM decklid but that still left all of the spoiler warning lights going off. I finally bought a 996 612 070 51 wiring harness and my warnings are gone. I am going to sell the OEM one.

Also, could you also please tell me the part number for the engine compartment light assembly (clear lens & bulb) that plugs into the blower fan for the 2003?

I tried to search these forums but did not find either of these part numbers in a search. I have also not found a consistent parts catalog online. If they exist, that would be good to know.

Thanks to everyone who contributes!

997.632.201.00 Engine compartment light -- US MSRP $5.61

999.631.018.90 Bulb for above -- US MSRP $6.32

That is the correct harness for an Aerokit car (996.612.070.51).

If you still have the stock harness the part number should be printed on it.

The part number was not on the harness. If / when I get this part number, I will post it to this thread.

Thank you for the help !
