97 Ram OD Button Wiring Help

ok so my 97 ram 4x4 has the OD button on the dash, so either its in 3rd or with the button off its in 4th/lock up. Sucks as you cant drive in that 40-65 range as it goes into lock up and lugs (but not during the time its in 4th before lock up).

So i found another "OD Off" switch and am going to install it next to the other one (no fog switch) and wire it for the lock up. Problem is i cant find any wiring diagrams for the factory dash OD switch.

My plan was to splice in the switch after the other od switch so i can have lock up only if 4th is allowed but controllable.

does anyone have a diagram of that switch? after i get it all together and working i'll ask a mod to make a sticky somewhere as its going to really help MPG around town and mpg for light towing.

thanks
Ed

EDIT: pic of stock OD and "hole" im going to install the second one in
