Like I said before, all 89-93 SCs and all 91-93 5.0 MN12s have the throttle body in the exact same place in the engine bay, and in the same place relative to the transmission, and all use the exact same TV cable. There is no difference in the intake manifold on the 5.0 from 91-93. If the cable you are using is shorter, then it is not from an SC, and it is the wrong part. It may be from a N/A V6 MN12, or it may be from a Mustang, or panther car, or something else, but if it is shorter, it is the wrong part, plain and simple. Making something that works is all well and good, if it really does put it exactly where it needs to be, but the AOD is extremely sensitive to the TV adjustment, and if it is off by just a tiny bit, you could well be replacing the trans again in a few thousand miles.
