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.

POST 1 / ORIGINAL POSTEROriginal post

Anyone ever replace the engine wiring harness? If so, anyone ever done it with the engine IN the car?

POST 2Original post

Definitely not the easiest thing in the world to do with the engine in...............

POST 3Original post

Trust me, you don't want to do that. I tried, and resorted to dropping the engine. It is so much easier access.

POST 4 / ORIGINAL POSTEROriginal post

I know, but was trying to be lazy about it. Might have the shop just do it when they do a couple other things on it.

POST 5Original post

Quotes source post: 639652

If you are paying a shop to do it, and they don't drop the engine, the cost just in labor time is going to skyrocket................

POST 6 / ORIGINAL POSTEROriginal post

I expect they will drop it if I have them do it

POST 7Original post

In my experience it comes down to just that....experience. If you have removed a harness from an engine that was out of the car, then you know how it was run and where the "hidden" connectors are and with that knowledge you can work around in the engine bay - assuming access above, below and through firewall - to change out the harness with the motor in the car. Are you working with a 2.7 out of a 2000? I ask because I once took a 2.7 out of a 2000 and tried to drop in a 2001 2.7 into that 2000. The wiring harness from the 2001 would not work seamlessly with the 2000 computers. One problem was the temperature sensor in the 2000 had four prongs, whereas the 01 had a two prong connector. A second problem was with the tiptronic thumb shifter not working. Once I took the harness off the 2000 2.7 and put it on the 01 2.7 everything worked fine again in the 2000. Good luck
