for the wiring up of the O/D and lockup look at the PATC webpage-----scroll down the page and you will see what they sell and how to do it----i bought the overpriced kit and installed it----i ended up disconnecting the vacuum disconnect as it seemed too sensitive---- the pressure switches used are available in transmission supply houses for the turbo 350 for about $10 each----i wired up a diesel dodge with an AC pressure switch and a toggle---it was good to go......
