i used catalog number 211 the first one u suggested and took one side to constant and one side to ground then the middle tested with the negative side of the dmm and brought the voltage to 2.5 into the pin. The only thing is that u have to test when the vehicle is running the batt rests at 12v and when running 14v so there is a bit of difference......seems to be working how long did it work before going into lock out mode before?
