Ok, I got-er installed and the vaccume line connected and all is well. Tranny shifts great and kicks down like it is supposed to. Now for the lockup part of it. This picture is if you were laying under truck with pan and filter removed. It seems to me that I need to run a hot wire to the plug on the positive side. It looks like it will get the negative when the pressure is right in the tranny. I dont understand why the pressure switch only has one terminal being used and if I hook up a negative to the plug then the solenoid would "always" have a ground. I think the only thing I need is the hot wire and that the negative on the plug is for something else but it just cant be that simple.
