just get an oil pressure switch, a normally open that closes with pressure, it needs an 1/8 inch npt i believe. wire it into 12v source and install switch on passenger side pressure port right behind servo this is 4th gear apply pressure, so when trans goes into 4th it will lock up. if you want you can even add another switch to open converter when u step on brakes or a throttle switch to open when you let off gas, but its not necessary and a lot of work.
