Here's the deal...... If you don't need the speed sensor for a fuel injection system, just the speedo. The stock cable from the C4 plug right into the tranny. If you need the speed sensor for a computer, just pull the end off the cable and yank the end off one in the junkyard and stuff it on your cable. That's what I did when I put the Fuel injected 5.0/AOD in my 68 Cougar and I did the same thing to hook the MG speedo to the T-5(Ford Turbo 2.3/T-5), in my MG
