Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
You'll also need to swap the ECU and possibly replace/re-pair lots of stuff.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 2Original post

Kinda cryptic. Are you swapping a 987 engine into a 986, or (shudder) a 986 engine into a 987? Here's a 987.1 wiring document. I have no info on a 986. You'll also need to swap the ECU and possibly replace/re-pair lots of stuff. Porsche 987.1 WIRING DIAGRAMS.pdf

POST 3Original post

Evening Chaps, I'm well on with a Cayman swap, but now desperately need the wiring diagrams to get this thing fired up. I noticed the diagram you posted is for the 2007, would this be the same as an 06? if not, would you have access to the relevant drawings? Kind regards Jason

POST 4Original post

I don't know but I would assume if not identical, they are very similar.

This is a source reference. Confirm exact model applicability in the original material.
