Noob question 727 really low shift points

Been down this road myself. Its one of the intricacies of owning a mopar eg. ballast resistors, external alternator regulator, ignition control modules. They are all fairly simple systems but if you are not familiar with them they can throw you for a loop and in this case shorten the life of your trans. If you didn't already, order the lokar bracket as well. I'm looking at your picture and it doesn't look like your current throttle cable bracket will have a place for the cable to hook up. Once you get it all installed be aware you will need to most likely adjust it. This means finding a straight stretch of road driving through the gears, pull over turn a quarter turn whichever way the instruction state then repeat. Took me about 6 passes to adjust the last time i did one.
