Re: 3.9mpi to 4.0ltr conversion pls hlp

we dropped an ED 6 into an EB wagon, just dropped it in and plugged in the existing plugs, there was one left over but we just ignored that and left it loose. Seems to work fine.

Don't take my word for it though because I think the engine had already changed from 3.9 to 4.0 and then we changed into a new 4.0 after that, so whether the wiring was changed originally I don't know, but I don't think it was.

MPI, EB-ED = no problems.
CFI = some wiring.
Enjoy!
