when I engage the 4x4 with the transfercase lever, the light doesn't illuminate. I have two LED lights in the bezel. I am getting 12v to the 4wd actuator. I replaced the actuator for a new 2FWDA1 actuator , which fits without mods. Yet the light does not illuminate on the bezel, ill try and drive home in 4x4 hi tonight and see if it comes on while driving. Transfercase engages the front driveshaft. Since i have power to the actuator, the fuse is obviously good, but I checked it anyway and it is good.
Does anyone know the pin out for the 4wd light connector?
I want to see if I can jump it to make the light come on and verify that there is no break or a bad led
