4x4 lights not staying on

[eclipseguy]

ok I have a 86 ranger super cab 2.9 manual with electronic shift transfer case. i got the 4x4 working but the only way i can get it to work is to unplug the pig tail on the module then the buttons work for a few secs then the lights go out and i have to unplug the pigtail and plug it back in to get it to turn back on so i can get out of 4x4. any one have any suggestion. the fuse is good. the motor is new and it works. but its weird. could it be a bad ground doing it?

I went out today and work on my 4X4 system. i have it narrowed down to the black/white wire on the pigtail. I can unplug and plug it back in to get the system to turn on. but it seems really weird that i have to do that to get it working. So i have the black and white wire hooked up to a momentary switch so i can get the system to work. I hope its something I'm just over looking. Once its in 4x4 it works just fine........ I just need to find a manual shift transfer case.
