Installing lockup switch
I have a 2003 dodge I'm running a built 47rh in. As of now it's got an Hgm Compushift mini for the standalone. I've tried contacting them to see if I can even do this with their controller but no response. What pin do I have to tap into on the sensor on the trans as I'm still using the manual pcm and all that good junk. Anything is helpful at this point as I'm about to freshen up the trans and get 2nd gear lockup enabled trying to get my 4 ton 2wd into the high 12's soon

A 47rh is only a 3 pin connector at the trans, the middle pin is constant 12 volts and the outer pins control lock up and OD. You can control them by running a wire from ground thru a switch and to those pins (2 separate switches) the simple way is with toggles but if you stop the truck with lock up engaged it tends to brake things. There are other simple ways of preventing this though
I have a write up in the regular 12 valve forum on this.
