simple wiring for 700r4

I read some where that you can run a wire from "A" to "D" and the lock-up will work. Now the letters may be wrong, but the main thing was it is plugged into one pin and to another. It was a jumper set up. One wire from one hole to another. Can anyone get me straighten out on the confirgeration for this and what it does? Thanks

your information would be incorrect.

you need 12 volts to the "A" terminal hole on the 4 hole connector.

A ground to the "D" is needed. If converter lock up happens depends on the design of the internal wire harness of the transmission

Here's a simple manual lockup system you can do. You can run a wire from term "A" to term "F" on your ALDL connector with a toggle switch, and lock up the converter In second gear on up (no lockup in first). Just remember to unlock it when decelerating or taking off from a stop to prevent damage to the converter.
