Had a 4R built to my intended specs w/full manual VB, input shaft, etc. Basically built for immediate installation so I haven't got many details on all of that. After installing the new converter, I had to pick up an MLP sensor from Ford along w/a transmission wiring harness from a 96+ Mustang which was mated to my stock harness for proper light operation/reverse lockout, etc. A Haynes manual told us what each wire on each harness was for, so that made short work of that.
If you want the name of the builder I used, let me know. After talking w/him at length on the phone prior to my build, I felt very comfortable with giving him the build job and having it shipped out to me.
