Need help. Got our 700R4 transmission worked on and were about to re-install it but cannot find the wiring for it. Where can we get it? Ideas

Did your truck have a 700 to begin with? What year is your truck?

Most all the pigtails are available from places like Rock. On mine, I got all new connectors, used what was left of the original with a wiring diagram and made a new one.
