997.1 C2 base. Bought the car with a fixed wing in it. I installed an eBay purchased rear decklid spoiler back on the car a while ago. I finally got the PIWIS coding back to normal at the shop today but the spoiler still doesn’t work. I also replaced the interior center stack switch button a bit ago so I know that’s not it. The issue is likely the harness I was told. Probably a fixed wing harness or the wiring just went bad. I can’t find a part number or the correct harness anywhere on suncoast etc…

1) Anybody who’s gone back to oem spoiler think there chance it’s something other than the wiring harness?
2) suggestions on how I find the original wiring harness part?

 

I might actually have that harness. Changed ours when we installed the TT decklid on my wife's c2s as we needed the connection for the hydraulics and spoiler brake light.

I'll need to check my spreadsheet to see if I sold it with the OEM decklid, but don't think I did.
