Re: MPI Conversion - PCM & Circuits Needed?
Unless you really want to do the wiring yourself---you might want to just skip the hassle of trying to wire up the original stuff and get a Hesco wiring harness. They have already figured out the PITA issues associated with the swap. I used the harness for my conversion and it was very well made and easy to hook up. The harness is labeled and if you have any questions, the tech support is excellent.
