The axle are in and working. I have install the locker control, dash switch, pump and completed proper wiring but still the locker dose not engage. Nothing happens when swith is turn on in the 4 wheel mode, no display light and pump dosen't run. I Think I need to install a locker pump relay or something. Seems like I missed somthing. Please help. <img src="/forums/images/graemlins/frown.gif" alt="" />
